78.20.-e - Opis:
- We report a systematic study of the temperature variation of the energy [E$\text{}_{0}$(T)] and broadening parameter [Γ$\text{}_{0}$(T)] of the fundamental band gap of ZnSe in the range 27 K < T < 370 K using contactless electroreflectance. The obtained values of E$\text{}_{0}$(T) and Γ$\text{}_{0}$(T) have been fit to various semi-empirical expressions to obtain information about the exciton-phonon coupling in this system. The experimentally determined E$\text{}_{0}$(T) also is of significance for technological applications since it can be used to determine the operating temperature of ZnSe-based devices such as quantum well lasers.
