Can carbon produce photoelectric effect? when use the laser wave 470nm. voltage between anode and cathnode is limited in the range -1 V to 1 V. Thanks~ Could you send the answer to Email: 3263490559 at qq.com
Only metals whih has valency of +1 and +2 are suitable for Photoelectric process.As they are in a rapid condition to take electrons to complete its octet.Thus are more eager to show photoelectric effect..Carbon has valency 4 which will take high enrhgy to release an elctron .Its Work function wouldd be so high that the power supplied would be even more than the energy it would provide thenrefore not suitable for Photoelectric process.
