Vapor-Transport Synthesis and Annealing Study of Zn _x Mg_1-x O Nanowire Arrays for Selective, Solar-Blind UV-C Detection.

ABSTRACT: This work uniquely reports the synthesis of Zn _x Mg_1-x O nanowires and submicron columns by utilizing a traditional carbothermal reduction process toward forming ZnO nanowire ultraviolet detectors, while simultaneously utilizing Mg₃N₂ as the source of Mg. To investigate the relationship between Mg content in the ZnO lattice and the cutoff wavelength for high spectral responsivity, the nanowires were annealed in a series of designed conditions, whereas chemical, nanostructural, and optoelectronic characteristics were compared before and after treatment. Postanneal scanning electron micrographs revealed a reduction of the average ensemble nanowire dimensions, which was correlated to the modification of ZnO lattice parameters stemming
