摘要: Abstract Optical absorption of free carriers in cadmium selenide was investigated by photoexcitation and, the case a strongly n -type sample, for equilibrium electrons as well. The dependence coefficient on wavelength confirms theoretical results concerning scattering arising from longitudinal optical phonons and impurities. Unambigous determination absolute values cross sections appeared to be impossible owing inhomogenities samples.
