Abstract

Spontaneous polarizations of GaN nanostructures and quantum dots are calculated for different surface terminations. In addition, dimensionally-confined phonons in GaN-based nanostructures are discussed. GaN-based nanostructures have applications in a variety of systems and concepts including: non-charge-transfer-based devices and single-photon detectors based on GaN-based double-barrier quantum-well injectors, conductive-polymer collectors, and colloidal quantum dot recombination regions. In this paper, application of photodetectors is considered along with the related application of using colloidal quantum-dot-based ensembles for solar cell applications.
