Photoconductive effect means
WebThis is called the photoelectric effect, meaning that light ( photo) produces electricity. One common use of the photoelectric effect is in light meters, such as those that adjust the automatic iris in various types of cameras. Another use is in solar cells, as you probably have in your calculator or have seen on a rooftop or a roadside sign. WebApr 2, 2024 · [21, 22] This therefore means that the EIT-related quantum effect can be classically mimicked in THz metamaterials. ... When the photoconductive antenna was irradiated by the fs laser, the THz-pulsed signals with width of several picoseconds were generated and, with the help of the photoconductive antenna detection, could be …

WebAll photoconductive cells exhibit a phenomenon known as hysteresis, light memory, or light history effect. Simply stated, a photocell tends to remember its most recent storage condition (light or dark) and its instantaneous conductance is a function of its previous condition. The magnitude of the light history effect depends upon the new light ...
