Abstract
An analysis of the experiments on the kinetics of the rise and decay of the current under the influence of extreme ultraviolet radiation on the indium–zinc oxide filament layer obtained by the electrospinning method is given. It is shown that the rate of rise of photocurrent is controlled by the radiation intensity and its decay rate is controlled by the partial pressure of oxygen on the surface of the wires. Owing to a significantly larger area of the active surface, this UV sensor with a layer of nanoscale wires has a shorter response time in comparison with homogeneous film structures in which the oxygen adsorption sites are concentrated.
