Web1. Introduction to Terahertz Photoconductive Antennas. Terahertz (THz) is the name given to the region of the electromagnetic spectrum lying between the microwave band (< 100 GHz) and the far infrared band (> 10 THz). 1 This region is often referred to as “the last frontier” for electromagnetic waves, since historically there has been comparatively little work … WebPhotoconductivity is an optical and electrical phenomenon in which a material becomes more electrically conductive due to the absorption of electromagnetic radiation such as visible light, ultraviolet light, infrared light, or gamma radiation.

WebThis means the photoconductivity increases that imply a decrease in photo resistivity of the material. Now that we have covered the working mechanism, we got an idea that a photoconductive material is used for the construction of a Photoresistor. According to the type of photoconductive material the Photoresistors are of two types.
