Dielectric constant model for environmental effects on the exciton energies of single wall carbon nanotubes (supporting online material, A. R. T. Nugraha et al., Appl. Phys. Lett., 2010) Supplement 1: Calculated Eii using the κ function for (n,m) SWNTs of the super-growth (SG) sample. 1.6 0.4 0.8 1 1 Here the explicit formula of κ for the SG sample is given by: 0.84 p 1.39 1.00 ; ...(S.1) d t lk where we have used the same origin for all the κ functions for different sample, that is 1.39 (see Fig. 2 of the paper). In the table below, the data are arranged in columns and categorized into metallic SWNTs, type-I semiconducting SWNTs, and type-II semiconducting SWNTs where mod( 2n m,3) 0, 1, 2 , respectively. The Eii data for different subbands p are listed, namely, E11M lower branch and E11M higher branch for metallic SWNTs, and E11S up to E44S for both type-I and type-II semiconducting SWNTs. Note that for metallic SWNTs, the density of states are splitted into lower and higher E11M. The diameter (dt) range in this table is from 0.7 to 3.0 nm.

You can also copy and save it to a separate excel file. You can calculate your own environmental transition energy ( E iienv ) for other surrounding materials. Use the following equation, which is related to Eq. (2) of the paper: E iienv E iiSG p ~ env C A B dt p C d t 2 ; ...(S.2) where A, B, and C are the fitting parameters given in the paper and EiiSG is given in the table above. ~ env As given in the paper, the C values for the super-growth (as-grown), alcohol-assisted CVD (as-grown), and HiPco (SDS) are 1.00, 1.42, and 1.52, respectively, where we fitted the optimized κ from Eii data based on resonance Raman spectroscopy (RRS) experiments. ~ We have also calculated the C env values for other surrounding materials and measurements by photoluminescence spectroscopy (not only from resonance RRS as ~ discussed in the present paper). The C env values are listed in the following table: Measurement Synthesis method (Environment) SG (as-grown) RRS AA-CVD (as-grown) HiPCO (SDS) a) HiPCO (SDS) a) PL AA-CVD (Hexane)b) AA CVD (Chloroform)b) C env 0.84 0.03 (R2=0.71) 1.19 0.02 (R2=0.90) 1.28 0.05 (R2=0.73) 1.29 0.05 1.49 0.04 1.73 0.06 ~ env C 1.00 0.03 (R2=0.71) 1.42 0.02 (R2=0.90) 1.52 0.05 (R2=0.73) 1.54 0.05 1.77 0.04 2.06 0.06 a) ~ The C env values from two different measurements (PL and RRS) are within their error bars. b) The experimental Eii values used in the optimized κ calculations are taken from Y. Ohno et al., phys. stat. sol. (b) 244, 4002 (2007). Supplement 2: Eii calculation from κ functions and comparison with experiment. In the following table, we give a simple illustration for a calculation of κ for the SG sample using Eq. (1) of the paper, or explicitly Eq. (S.1) of this supplemental material. The κ value thus obtained then specifies a unique E ii value from our exciton program (see J. Jiang et al., Phys. Rev. B 75, 035407, 2007 and K. Sato et al., Phys. Rev. B 76, 195446, 2007).
