Photoconductivity ppt

WebPhotoconductivity is the increase in electrical conductivity of a material that takes place when the material is illuminated with infrared, visible, or ultraviolet light. The absorption of light is a quantum process in which electrons are excited to higher energy levels. Ordinarily, the excited electrons are more mobile than unexcited electrons. WebFigure 1: The energy gap seen between the superconduct-ing state (top) and the normal state (bottom) produces the order parameter of the system.

WebApplications: Figure 20-13 shows a photoconductive cell used for relay control. When the cell is illuminated, its resistance is low and the relay current is at its maximum. Thus, the relay is energized. When the cell is dark, its high resistance keeps the current down to a level too low to energize the relay. Resistance R 1 is included to limit ...
