Ph.D. Research
[1] Studying nano-scale structure of nanoparticles using the atomic pair distribution function
(PDF) technique. A quantitative study of atomic scale structure is a prerequisite to
understand material properties in general. However, the atomic structures of nanoparticles and
nanostructured materials are not accessible by conventional methods used on crystalline
materials because, by their nature, nanostructured materials are not periodically long-range
ordered and subjected to local structure deviations comparing to bulk. Part of my Ph.D.
research is to employ the PDF method to quantitatively study nano-scale structure of
nanoparticles. The goal of this study is not only to explain the PDF data of CdSe nanoparticles
through a modeling process, but also to systematically investigate the sensitivity of the PDF
data to subtle structural modifications in nanoparticles relative to bulk material and establish a
PDF based methodology to quantitatively study nanostructure materials in general.
