ResumoAbstract The electronic structures of single-layer Mo 1− x Cr x S 2 are calculated by the spin-polarized density functional method. Single-layer Mo 1− x Cr x S 2 exhibits a direct band gap for any Cr concentration ( x ). The energy band gap monotonically decreases as a function of x and takes an ideal value for photovoltaic applications at x ≃ 0.23.
