摘要
An optical-absorption study of synthetic RuTe2 single crystals is reported over a temperature range from 4.2 to 350 K. The analysis of the absorption curves reveals that the interband transitions in RuTe2 are indirect. The indirect band gap of various temperatures are determined and its temperature dependence are analyzed by the Varshni equation [Physica 34, 149 (1967)] and an empirical expression proposed by O'Donnell and Chen [Appl. Phys. Lett. 58, 2924 (1991)]. The parameters that describe the temperature dependence of energy gap of RuTe2 are evaluated and discussed.
