Computational Modeling of the Size Effects on the Optical Vibrational Modes of H-Terminated Ge Nanostructures
The vibrational dispersion relations of porous germanium (pGe) and germanium nanowires (GeNWs) were calculated using the ab initio density functional perturbation theory with a generalized gradient approximation with norm-conserving pseudopotentials. Both pores and nanowires were modeled using the s...
