Tests on far UV irradiation of CVD diamond

We present the results of UV irradiation of samples of CVD diamonds films in terms of time response and current–voltage curves. In this paper we describe the samples and the studied method. This brings us to conclusions on the defect sites. We have extensively studied the charge up effect of the film and the influence on the detection efficiency. We find a dependence on the irradiation time and methods, which questions directly a photon detector based on synthetic diamond films.
