Bandgap atomistic calculations on hydrogen-passivated GeSi nanocrystals
We present a detailed study regarding the bandgap dependence on diameter and composition of spherical Ge-rich Ge(x)Si(1−x) nanocrystals (NCs). For this, we conducted a series of atomistic density functional theory (DFT) calculations on H-passivated NCs of Ge-rich GeSi random alloys, with Ge atomic c...
