Capacitance-voltage characterization of commercial gallium nitride diodes subjected to electron radiation

The effects of electron radiation on commercially fabricated gallium nitride light emitting diodes (LEDs) is of interest due to its high tolerance against temperature and high breakdown voltage, making it suitable to be used in an extreme environment. LED based on this material is used as part of...

LED based on this material is used as part of visible light communication and as an illuminating source in space.

Capacitance-voltage (C-V) characteristics of commercial GaN LEDs before and after irradiation were investigated. As the radiation dose increase, the amount of capacitance and doping concentration decreases. This is believed due to deactivation of dopants atoms in the bulk.
