Spectral dispersions of index of refraction $${n(\lambda )}$$n(λ) and extinction coefficient $${\kappa (\lambda )}$$κ(λ) of undoped amorphous selenium (a-Se) films of three thicknesses (d ≈ 0.5, 0.75, and 1.0 µm) were evaluated by analyzing experimental room-temperature normal-incidence transmittance-wavelength ($${{T_{{\text{exp}}}}(\lambda )} - \lambda$$Texp(λ)-λ) data (λ = 400–1100 µm) of their air-supported {a-Se film/thick glass slide}-stacks using Swanepoel’s transmission envelope theory… Expand
