H10F 30/221 the potential barrier being a PN homojunction
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 > the potential barrier being a PN homojunction
