Photodiode Vs Photocathode. The older classical types consist of thin evaporated layers of alkali metals. Some detectors, such as photodiode arrays, which use multiple detector elements arranged to gather spatial information, can have response times. The pmt (figure 1) consists of a photosensitive surface (photocathode), electron multipliers (dynodes), and a collection. Phototubes and photodiodes make up one main class of photodetector types, and they are based on the photoelectric effect, which states that an electron will be liberated from a metal surface if the energy of the photon striking the surface is greater than the the work function of the surface. Two types of photocathode are used in practice. A photocathode is an electrode made from a photoemissive material from which electrons can be released into free space via the external photoelectric effect. Photodiodes are semiconductor devices exploiting the internal photoelectric effect, as opposed to the photoemission taking place in a photocathode. The photocathode the response of a pmt to light is specified by its photocathode sensitivity which can be specified by several ways:
