Anisotropic behavior of excitons in single-crystal α-SnS
We investigate analytically the anisotropic dielectric properties of single-crystal α-SnS near the fundamental absorption edge by considering atomic orbitals. Most striking is the excitonic feature in the armchair- (b-) axis direction, which is particularly prominent at low temperatures. To determin...
