Description

Flat Sapphire 4 Inch Blue LED GaN Epitaxial Wafer On Sapphire SSP

4 inch Blue LED GaN epitaxial wafer on sapphire SSP

The operation principle of LEDs is based on the semiconductor PN-junction. A PN-junction in a semiconductor is interface between two semiconductor regions of different doping. p-side is doped with acceptor impurities such as Boron which have one less valence electron compared to the semiconductor valence shell and N-side is doped with donor impurities such as Phosphorus which have one extra electron on valence shell compared to the semiconductor.
