CaGa2Se4–GaSe system
Source abstract
Abstract
The phase relations in the CaGa2S4–GaSe system have been studied using differential thermal analysis, X-ray diffraction, microstructural analysis, microhardness tests, and density measurements, and its T–x phase diagram has been mapped out. The CaGa2S4–GaSe system has been shown to be a pseudobinary join of the ternary system Ca–Ga–Se. The CaGa2S4–GaSe system has been found to contain limited solid solutions based on the constituent selenides. The electrical conductivity of CaGa2S4 has been measured and its current–light behavior and photoelectric properties have been studied.
