We show that wide GaN quantum wells behave like mesoscopic capacitors. The electron-hole pairs, are separated by the spontaneous and piezoelectric polarization fields and accumulated in the well. resulting in a well width dependent screening of the built-in field.

Abstract
We show that wide GaN quantum wells behave like mesoscopic capacitors. The electron-hole pairs, are separated by the spontaneous and piezoelectric polarization fields and accumulated in the well. resulting in a well width dependent screening of the built-in field.File in questo prodotto:
