The article discusses technical hurdles that should be addressed before substituting silicon for sapphire in manufacturing Light Emitting Diode (LEDs). It provides detail information on structure Lighting LED devices, which are fabricated on gallium nitride (GaN) semiconductor layers. The author also tells that silicon wafers are cheaper than sapphire and lighting LEDs grown on silicon wafers will be as good as LEDs developed on sapphire.
