DIFF Subgroup
H10F 30/22 the devices having only one potential barrier, e.g. photodiodes
Introduced: January 2025
Full Title
Individual radiation-sensitive semiconductor devices in which radiation controls the flow of current through the devices, e.g. photodetectors > the devices having potential barriers, e.g. phototransistors > the devices being sensitive to infrared, visible or ultraviolet radiation > the devices having only one potential barrier, e.g. photodiodes
