Lead selenide is a semiconductor material that forms cubic crystals of the NaCl structure. It performs efficiently at low temperature without the need for cooling. It naturally occurs in the mineral clausthalite.
Silicon-germanium is a general term for Si1-xGex alloy that consists of any molar ratio of germanium and silicon. It is manufactured on silicon wafers by using conventional silicon processing toolsets.
Tin dioxide is an inorganic compound with the chemical formula SnO2. It mainly occurs in the mineral, cassiterite. It is a colorless, amphoteric and diamagnetic solid that is usually considered as an oxygen-deficient n-type semiconductor.
Stellite alloys are a group of cobalt-chromium 'super-alloys' consisting of complex carbides in an alloy matrix predominantly designed for high wear resistance and superior chemical and corrosion performance in hostile environments.
