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.
