Polarization dilution in a Ga-polar UV-LED to reduce the influence of polariz…

We investigated the influence of polarization charges in nitride-based semiconductors. The influence due to polarization charges was calculated excluding the influences of the band offset. We found that the polarization charges (1
1013 cm2) resulted in an energy spike of more than 100 meV at the location of the charges, which is a similar value to the band offset. We then proposed the concept …
