· JVASP-17255· Cu2GeSe4

Cu2GeSe4 is a quaternary chalcogenide compound belonging to the family of copper-based semiconductor materials with potential thermoelectric and photovoltaic properties. This is primarily a research material rather than an established commercial alloy, investigated for applications where semiconducting behavior, moderate mechanical stiffness, and thermal management capabilities are needed. The material's relatively high density and mixed-metal composition make it of particular interest in solid-state physics research and emerging technologies seeking alternatives to conventional semiconductors or thermoelectric materials.
