Two-dimensional cubic phase Ga2O3 with highly anisotropic mobility and robust wide-bandgap
The electronic and transport properties of the two-dimensional (2D) cubic-Ga2O3 are systematically explored using Heyd–Scuseria–Ernzerhof (HSE) and Perdew–Burke–Ernzerhof functionals, as well as deformation potential theory, indicating the superior structural stability of the cubic monolayer compared with that of cleav...
