Book excerpt: Chalcogenide glass is made up of many elements from the Chalcogenide group. The glass is transparent to infrared light and is useful as a semiconductor in many electronic devices. For example, chalcogenide glass fibers are a component of devices used to perform laser surgery. Semiconducting Chalcogenide Glass III: Applications of Chalcogenide Glasses is a comprehensive overview of designs of various chalcogenide glass devices are presented, including switches, phase inverters, voltage stabilizers, oscillators, indicators and display control circuits, memory devices, and sensors. A special chapter is devoted to chalcogenide glass applications in optical fibers. This collective monograph is intended to survey the current state of chalcogenide glass applications to facilitate further development. - The first collective monograph written by Eastern European scientists covering electrical and optical properties of chalcogenide vitreous semiconductors (CVS) - Contributions by B.G. Kolomiets, who discovered the properties of chalcogenide glass in 1955! - Provides evidence and discussion by authors from opposing positions
