Further investigation on the growth mechanism, the surface state, the optical behavior, the transport properties and the device applications will be carried on. A proposal entitled “N-Based III-V Semiconductor Nanostructures “ has been granted as National Science and Technology Program for Nanoscience and Nanotechnology by National Science Council in Taiwan. In the nano-dots filed, spherical and well-separated W nano-dots embedded in the SiO2 layer are demonstrated for the first time to be used as the low-power nonvolatile memory device. The tungsten dots are formed with a mean size and aerial density of 4.5 nm and 3.71011/cm2, respectively. The band diagrams of “write” and “erase” operate with different gate polarities of the memory device with W nano-dots. A significant C-V hysteresis of Vt shift of 0.95 V was observed and the endurance of the memory device was not degraded up to 106 write/erase cycles. In addition, a nonvolatile memory device embedded with Ge nano-dots is fabricated by the thermal oxidation of Si0.8Ge0.2 . The tunnel oxide in the nonvolatile memory is controlled to be 4.5 nm-thick and embedded with 5.5-nm Ge nano-dots. A low operating voltage, 5V, is implemented and a significant threshold-voltage shift, 0.42V, is observed. When the electrons are trapped in the Ge nanocrystals, the effect of Coulomb blockade prevents the injection and storage of more electrons and decreases the leakage current. In the nano-wire filed, we have successfully fabricated polycrystalline silicon thin-film transistors (poly-Si TFTs) with multiple nano-wire channels. The channel length and width are 0.5 um and 67 nm, respectively. Superior electrical characteristics, such as higher ON/OFF current ratio (>108), better subthreshold slop (SS) of 110mV/decade, free of drain induced barrier lowing (DIBL), and suppressed kink-effect, can be achieved, compared to the single channel TFTs. This will be promising for the proposed TFTs device with nano-wire channels to be applied to active matrix liquid crystal display technologies. Also, this project has been granted recently as National Science and Technology Program for Nanoscience and Nanotechnology by National Science Council in Taiwan. (b) Spintronics in Oxide Since the discovery of Giant Magnetoresistance (GMR) in the Fe and Cr multiplayer system the conduction of polarized carrier (the spintronics) raises massive attention in application especially in the read-head. The recent development of of Tunneling Magnetoresistance (TMR) with MR higher than GMR exhibits great capability in Magnetic Random Access Memory (MRAM). Though the colossal Magnetoresistance (CMR) has a colossal MR signal at high magnetic field of few Tesla, its low Cure’s temperature (Tc) and high cerosivity makes it less applicable in application. Up to date, the TMR is base on magnetic metal mostly, only few example has shown high low-field MR on CMR. However, the insulator layer in TMR has to be very thin, free of pin-holes and smooth to prevent from scattering and result in loss polarization properties. If there has magnetic impurities in the insulator layer, the polarized carrier will experience the spin flip during tunneling and than lower the MR. Eventhough the extra ferromagnetic layer inside the insulator layer may enhance the MR, it creates only on the complexity of the processing. In our preliminary experiment, a magnetic insulator with subsequence superstructure was mixed with ferromagnetic CMR bulk, the low-field magnetoresistance was dramatically enhanced. The further research direction will apply this idea in films. The goal of this project is objectively to overcome these problems in CMR and to development (1) a single device exhibited the low-field MR and (2) the full oxide PN junctions and transistors. (c) Nanoclustering Imperfect oriented attachment of nanoparticles over specific surfaces is rationalized to cause accretion and defects for the rutile condensates. Analytical electron microscopy indicates that rutile nanoparticles prepared by Nd:YAG laser ablation on Ti targets have well-developed {110} and {011} surfaces with steps. These surfaces are beneficial to {similar to110} and {similar to011} vicinal attachment, causing, respectively, edge dislocations and planar defects, i.e., fault and twin for rutile crystal. The {011}-interface relaxation, by shearing along <011> directions, accounts for a rather high density of edge dislocations near the planar defects thus formed. Brownian motion may proceed above a critical temperature for anchorage release at the interface of imperfect attached nanoparticles until an epitaxial relationship is reached. Also, Imperfect oriented attachment of nanoparticles over specific surfaces is rationalized to cause accretion and defects for the hexagonal inorganic surfactant mesophase. Analytical electron microscopy indicates that silicate MCM-41 particles, prepared in alkaline hydrothermal condition and then surfactant (cetyltrimethylammonium bromide) leached, have well-developed {10} surfaces with monolayer steps and a rather uniform base with constant tubular wall thickness. These surfaces are beneficial to {similar to10} vicinal and head-on attachment, causing respectively edge dislocation and twist boundary for hexagonal silicatropic liquid crystal. Brownian motion may proceed above a critical temperature for anchorage release at the interface of imperfectly attached particles until an epitaxial relationship is reached. This project was the first granted project as National Science and Technology Program for Nanoscience and Nanotechnology by National Science Council in Taiwan based on his achievement published in Science (d) Nanocomposites The majority of current applications of the nano technology appear to be the nano materials, especially nano powders. 3D bulk materials and composites are still under the research stage. Limited successful results are all focused on the polymer matrix composites with the semi-uniform dispersion of nano ceramic particles. This subproject is aimed on the synthetize, aggregation, phase transformation and the motion of nano-particles., and on the fabrication and characterization of nano-cluster, light-weight metallic nano materials and composites. The matrix materials are based on Mg, Al, Ti, or Zr. The processing means are in two folds; one through the top-down and the other through the bottom-up routes. Through various top-down processing methods, the grain size can be effectively refined from 100 m down to 3 nm or below, from which level sudden transformation into isotropic and amorphous state will occur. On the other hand, through the bottom-up methods by rapid quenching via drop-melting or melt-spinning, complete amorphous matrix will be yielded, from which uniform nano phase measuring 1-100 nm could be obtained. In cooperation with Cheng Kung University, nanocomposites based on the above matrix will be fabricated through the advanced concurrent co-spray forming technique. Nanoceramic particles, wires, or tubes will be sprayed together or parallel with the matrix materials. High performance Mg based nano composites, not reported previously worldwide, can be prepared in our laboratory. (e) Molecular wiring and motors The spectroscopic and electrochemical characterizations of electrochemically stable biferrocene-modified Au clusters and chemisorbed biferrocenylalkanethiols on Au(111) surface were studied. Two successive reversible one-electron redox waves were observed for the biferrocenylalkanethiol Au nanoclusters and biferrocenylalkanethiol monolayers on Au(111) surface in the cyclic voltammetry. Furthermore, the positive and negative current peaks for each redox wave occur at almost the same potential, and the peak current increases almost linearly with the sweep rate. Repeat scanning does not change the voltammograms, demonstrating that these monolayers are stable to electrochemical cycling. The coverages of electroactive biferrocene in the monolayers were calculated from the cyclic voltammograms. The standard electron-transfer rate constant was calculated from the splitting between the oxidation and reduction peaks. The preparations of multinuclear supramolecules assembled from 1’,1’’’-bis (terpyridyl)biferrocene redox-active subunit with Ru(II) metal centers are described. The appreciable variations detected in the Fe2+/Fe3+ oxidation potentials indicate that there is an interaction between the spacer and terminal ferrocenyl moieties. Molecules that involve spontaneous bond formation between metals and multidentate ligands that have potentially versatile coordination modes were also studied. One fascinating phenomenon discovered in Professor Liang’s laboratory is the formation of double helical molecules mediated by selected metals that inherently adopt a tetrahedral geometry. For instance, addition of dibutylmagnesium or diethylzinc to a THF solution of N,N’-ethylenedi(5-tert-butyl-pyrrol-2-ylaldimine) generates the double helical dinuclear metal complexes. Highlight of some research results State-of-art extra low dislocation density 2-in LAO single crystal, the next generation substrate to grow GaN LED, TEM(lattice image -PbO2-type, anatase and rutile structure) of titania particles generated by laser-ablation condensation,. Scale bar, 50 nm. in PRL The nano-capillary brings within it a huge imbalance in equilibrium partial pressure of Ga relative to the growth ambient.
