Direct to indirect band gap transition in two-dimensional germanium carbide through Si substitution
In this work, the structural, electronic and optical properties of Si substituted single-layer GeC are studied by performing density functional theory calculations. Single-layer GeC possesses a direct band gap of 2.11 eV at the K point. The direct band gap feature in single-layer GeC does not change...
