Abstract

Density functional theory combined with non-equilibrium Green’s function approach was applied to study the electrical and thermal properties of ternary 2D GaAs_1−x P_x (x = 0.0, 0.25, 0.50, 0.75, 1.00) attached to 2D germanene electrodes. The dependence of the electrical conductance, IV characteristics and thermopower on the concentration of phosphorene was investigated in depth. The increased presence of P supports the impedance towards moving electrons and consequently reduces the forward and backward currents, and thermopower.
