WebNov 19, 2024 · Dark current was defined as the median of DCS. The density of O precipitate defects, called bulk microdefects (BMDs), in the CZ-Si substrate and the concentration depth profiles of the metallic impurities C, O, and H were measured on samples that underwent DCS measurements. WebApr 12, 2024 · Image dehazing has always been one of the main areas of research in image processing. The traditional dark channel prior algorithm (DCP) has some shortcomings, such as incomplete fog removal and excessively dark images. In order to obtain haze-free images with high quality, a hybrid dark channel prior (HDCP) algorithm is proposed in … WebNov 10, 2024 · The dark current spectroscopy can be used to determine the defects present by monitoring the currents of the current dark-temperature histogram evolution.
