The exciton Bohr radius of bulk Ge is larger than that of Si, hence resulting more prominent quantum size effects. In this work, the electron structure of Ge nanocrystals is studied by means a sp³s* tight binding approximation. Comparing the theoretical calculations with experimental data, we conclu...
