Abstract

Gallium nitride has become one of the most attractive materials for light emitting devices and high-temperature and high-power devices,due to its superior opto-electronic properties. Ohmic contact is a critical technology for preparing GaN based devices. In this paper,research progress in ohmic contacts in n-GaN and p-GaN is presented emphatically.
