First-principles study of structural, electronic, and optical properties of surface defects in GaAs(001) - β2(2x4)

We performed first-principles calculations based on density functional theory (DFT) to investigate the role of point defects in the structural, electronic, and optical properties of the GaAs(001)- β2(2x4). In terms of structural properties, AsGa is the most stable defect structure, consistent with e...
