摘要：

The fundamental absorption of GaSb, experimentally investigated by optical transmission measurements performed in the temperature range 9-300 K on nominally undoped molecular-beam-epitaxy-grown GaSb layers, is compared to theory. Calculations related to a band-to-band optical transition theory based on the models of Kane and Elliott, considering the band nonparabolicity and the electron-hole (exciton) interaction effects, respectively, show excellent agreement with experimental results. The role of different contributions to absorption coefficient is discussed.
