Abstract

The room teffiperature stiniulated emission near ultraviolet from ntype GaN film which was grown by MOVPE on a sapphire substrate is observed for the first time. The low energy electron beam irradiation treatment lowers the resistivity of Mgdoped GaN which tends to show p-type conduction and simultaneously enhances blue luminescence efficiency drastically. The pn junction LED shows strong both nearbandedge UV ends sion from nlayer and blue emission from player.
