Abstract
Low temperature electroluminescence (EL) from a ZnO nanowire light emitting arrays is reported. By inserting a thin MgO current blocking layer in between ZnO nanowire and p- GaN, high purity UV (ultra-violet) light emission at wavelength 398nm was obtained. As the temperature is decreased, contrary to the typical GaN based light emitting didoes (LEDs), our device shows a decrease of optical output intensity. The results are associated with various carrier tunneling processes and frozen of MgO defects.
