Band Parameters of Two-Dimensional Materials: Phosphorene and Silicene

ORAL

Abstract

The method of invariant is used to derive effective Hamiltonians in the presence of strain and external fields for phosphorene and silicene as examples of two-dimensional materials with and without a band gap. The band structure parameters have been obtained by fitting to density-functional theory calculations.
