摘要
We report on direct wafer bonding of an n-type ZnO wafer to a III-nitride light-emitting diode (LED) structure. Wafers were successfully bonded in nitrogen at 600 degrees C. ZnO was then selectively etched to form a p-type electrode having a truncated hexagonal pyramid shape. This wafer bonded LED was evaluated with transmission, reflectivity, current-voltage (I-V), and electroluminescence (EL) measurements. This electrode revealed to be highly transparent and suitable for improving light extraction.
