Cesium Telluride (Cs-Te)

Semiconductor

Description

Cesium Telluride (Cs-Te) is a semiconductor typically formed in thin films by deposition of Cs and Te on a substrate. It is a popular choice of UV photocathode because although it has a high quantum efficiency that comes with being a semiconductor photocathode, it tends to also have a high lifetime and tolerate poor vacuum conditions. This makes it well-suited for applications that require low downtime such as accelerator user facilities.
