Light can be produced and/or controlled electronically in a number of ways. In light emitting diodes (LEDs), ... Between p-type and n-type semiconductor layers, an active region emits light when an electron and hole recombine. Considering the p-n combination to be a diode,then when the diode is forward biased, holes from the...
