OPTICAL PROPERTIES OF ZnGa₂Se₄ COMPOUND

Kh.O. Sadig, Sh.R. Mammadova

ABSTRACT

In this study, the optical properties of the ZnGa₂Se₄ single crystal were comprehensively examined. X-ray diffraction (XRD) analysis confirmed that the compound is single-phase and crystallizes in a tetragonal structure belonging to the I4₂m space group. Furthermore, detailed analysis of spectroscopic ellipsometry measurements revealed that the material exhibits a direct band gap with an energy of 2.81 eV.

Keywords: ZnGa₂Se₄, spectroscopic ellipsometry, band gap width.
