Abstract
Capacitance measurements on thin, fully depleted GaSe samples indicate a low frequency dielectric constant ϵ_0 = 8.0 ± 0.3 for E||c. Infrared reflectivity measurements show a single resonance for each polarization of the electric vector. Dispersion analysis gives ϵ_∞ = 7.1 and ϵ_0 = 7.6 for E||c and ϵ_∞ = 8.4 and ϵ_0 = 10.2 for E⊥c. More accurate channel spectra give ϵ_∞ = 7.45 and ϵ_0 = 9.80 for E⊥c. A number of weak two phonon combination bands are observed.
