Two-Dimensional Tetrahex-GeC 2 : A Material with Tunable Electronic and Optical Properties Combined with Ultrahigh Carrier Mobility

Based on first-principles calculations, we propose a novel two-dimensional (2D) germanium carbide, tetrahex-GeC , and determine its electronic and optical properties. Each Ge atom binds to four C atoms, in contrast to the known 2D hexagonal germanium carbides. Monolayer tetrahex-GeC possesses a narr...
