Abstract
Indium Tin Oxide (ITO) films are widely used on LED chips nowadays for the applications on ohmic contacts and current diffusion layer of p-GaN. However, ITO film is limited by the high cost and poison, it´s necessary to be instead. The transparent conductive oxide basic on Zinc oxide is one of the best choices. In this paper, a muti-structure, ITO/GZO films were carried out for an instead of ITO films. It was found ITO (5nm)/GZO films could improve the luminous intensity of LED chips with an ideal turn-on voltage. Compared to the LED chips with ITO films, the luminosity of LED chips with ITO (5nm)/GZO were improved by 5%.
