The as-measured room-temperature normal-incidence transmittance–wavelength (Texp(λ) − λ) spectra of undoped amorphous selenium (a-Se) films, which were thermally deposited onto glass slides, exhibit well-resolved interference-fringe maxima and minima λ > λc (≈630 nm), below which they fall rather sharply to zero transmittance. In the transparency and weak absorption region, the maxima transmittance is close to the substrate transmission, implying good uniformity of the a-Se films. The geometric…
