Gallium nitride nanoparticles for solar-blind detectors

Article

Abstract

We investigate the properties of GaN semiconducting nanoparticles as a potential candidate for photodetection in the solar-blind region. The photocurrent spectral response is studied spanning the range 1.6-5.5 eV. A significant fraction of the response is in the range 4–5.5 eV. The results are compared to other optical properties and the origins of the features observed in the spectra are speculated upon.
