(Color online) Calculated band structure of SnS along Γ-X (along a-axis), Γ-Y (along b-axis), and Γ-Z (along c-axis). Large red dots represent valence band maximum and conduction band minimum. Crystal structure of SnS: small yellow spheres represent S atoms, while large grey spheres represent Sn atoms.
(Color online) Measured (light red) and calculated (dark blue) absorption spectra of SnS, with (solid) and without (dashed) excitonic effects.
(Color online) Calculated defect formation enthalpies for intrinsic defects in S-rich (left panel) and Sn-rich (right panel) limits in SnS.
(Color online) Measured (blue squares) and calculated (red lines) hole concentrations between the limiting Sn-rich and S-rich growth conditions.
