Growth and characterization of ZnO nanostructures for UV sensor applications

E-O Sensors are being developed for a variety of Military Systems Applications. These include UV, Visible, SWIR, MWIR and LWIR Nano Sensors. In this paper, we will discuss growth and characterization of ZnO Nanowires on a variety of substrates that include Silicon, ZnO and flexible substrates. The critical technologies being developed include ZnO nanostructures with wide band gap for UV detection for a variety of threat warning applications. We will present experimental results on the structural, electrical and optical properties of ZnO nanowire for UV detectors. Experimental results on ZnO based nanostructures demonstrate enhanced UV sensitivity and path forward for larger arrays.
