(Color online) QP bands in the approach at the point without (dotted lines) and with (solid lines) spin-orbit interaction vs biaxial strain. The level (without SOC) and the (with SOC) are taken as energy zero.
(Color online) Binding energies (solid lines, circles) and oscillator strengths (dashed lines, squares) vs biaxial strain of (blue), (red), and (green) excitons.
Gap (in eV), energy splittings of valence bands, and exciton binding energies (in meV) at the equilibrium coordinates as well as their linear biaxial strain (in eV) and stress (in meV/kbar) coefficients.
