Effect of Polarity on the Electrical Properties and Low-Frequency Noise Characteristics of LEDs Grown on Sapphire Substrates

Abstract In this study, the electrical properties, photoluminescence spectra and the low-frequency noise behaviors of the polar, semipolar, and nonpolar AlGaN-based UV LEDs grown on the sapphire substrate have been measured and investigated at room temperature. The electrical par...
