(a) Comparison of XANES spectra for as-prepared Ge QDs, amorphous Ge (Backman et al., 2009) and bulk diamond-type Ge. (b) Illustration of the calculation cluster including different local coordination shells. (c) Simulated XANES spectra for diamond-type Ge structure by FDMNES using FDM mode, where the calculation cluster size was set from 3.0 Å to 7.0 Å. The arrows indicate the second main feature position in each spectrum. |
