diode, junction rectifier, semiconductor diode
LED, light-emitting diode
diode such that light emitted at a p-n junction is proportional to the bias current; color depends on the material used
OLED, organic light-emitting diode
a self-luminous diode (it glows when an electrical field is applied to the electrodes) that does not require backlighting or diffusers
semiconductor, semiconductor device, semiconductor unit
a conductor made with semiconducting material
