Development of UV Photo Detector : ZnO nanostructure
Nanoscale materials have shown unprecedented capabilities in the emerging technologies ranging from solar energy harvesting to biosensing. New applications for nanophotonics and nanoelectronics are been inspired by the development of defect-free low-dimensional nanostructures.To assess their potential capabilities is particularly important to uncover their new and interesting properties and characteristics concerning electronic transport, light emission and photo-detection. The low dimensionality and the high surface-to –volume ratio play a fundamental role in the overall photo-detection performance . An important attribute of photoconductors is their ability to produce gain in the excess of one that is the generation of more than one electron in an external circuit for each absorbed photons. The direct band-gap materials other than ZnO have a lower propensity to trap charge carriers, and nanostructures of these materials are, in ge...
