Abstract

The electronic structures of germanium cluster (Ge_n; n=4-32) were studied by using photoelectron spectroscopy (PES) for Ge_n^-, Ge_nF^-, and Ge_nCl^-. The halogen atom doping method enables us to determine the HOMO-LUMO gap of the corresponding neutral Ge_n cluster to be 0.8-1.0 eV around n=30. This result implies that the Ge_n cluster itself never emits visible emissions.
