Chalcogenide materials are a class of compounds that contain elements from the VI group of the periodic table, namely sulfur, selenium, and tellurium. These materials have unique properties that make them suitable for a wide range of applications, such as in electronics, photonics, and thermoelectrics. Chalcogenide materials possess interesting properties such as high refractive index, low optical losses, and tunable electronic properties. They can be used to create devices such as phase-change memory, infrared sensors, and photovoltaic cells. Research in chalcogenide materials aims to further understand their properties and potential applications, as well as to develop new materials with enhanced characteristics. This field is interdisciplinary, involving chemistry, physics, materials science, and engineering. The study of chalcogenide materials continues to be an active area of research due to their promising technological applications.
