Polarization fields in nitride nanostructures: theory and practical implications
Fabio Bernardini, Vincenzo Fiorentini
Abstract
Huge built-in electric fields are predicted to exist in wurtzite III-V nitrides thin films and multilayers. Such fields originate from heterointerface discontinuities of the macroscopic bulk polarization of the nitrides. We discuss the theoretical background and the intriguing practical implications of polarization fields for nitride nanostructures.
