Light emission based on the excitation of rare gases by a low energy dc electron beam is a promising approach for realizing deep- or vacuum-ultraviolet light sources or lasers that are compact and have high efficiency. Carbon nanotube (CNT) field emitters have been used as electron sources in replacement of thermal cathodes to construct a low energy-consumption, compact and low-cost system. However,...
In this paper, a CdTe X-ray sensing device which consists of a CdTe pin diode and a field emitter is fabricated. The CdTe pin diode was fabricated by an excimer laser doping method, which was applied to form an n-type CdTe layer. An indium thin layer was evaporated on the p-type CdTe as a dopant material, and then an n-type CdTe layer was formed by irradiating a KrF laser to the dopant layer in a...
