It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction. … When a diode is reverse-biased, it acts as an insulator and does not permit current to flow. What is diffusion and drift current? simple energy facebookWebSemiconductor detectors. When a charged particle loses its energy in a solid rather than a gas, processes similar to ionization and excitation also take place. In most solids or liquids, however, the resulting electrical charges cannot be transported over appreciable distances and thus cannot serve as the basis of an electrical signal. simple energy inc
