1. Willoughby Smith discovered the photoconductivity of the element selenium in 1873. 2. His work followed the discovery of photoconductivity in selenium by Willoughby Smith in 1873. 3. The equation for photoconductivity substitutes the parameters of the incident light for ? and is 4. Whereas other Se forms are insulators, gray Se is a semiconductor showing appreciable photoconductivity . 5. Near zero carrier density graphene exhibits positive photoconductivity and negative photoconductivity at high carrier density. 6. Near zero carrier density graphene exhibits positive photoconductivity and negative photoconductivity at high carrier density. 7. The underlying phenomenon is called sensitized photoconductivity . 8. Rose was an expert on photoconductivity . 9. Combined with the photoeffect and photoconductivity , the electro-optic effect gives rise to the photorefractive effect. 10. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity .
