It’s a remarkable material with exceptional properties, including high electrical conductivity and mechanical strength. One of its key characteristics is its work function.
Work Function of Graphene
The work function of graphene is highly sensitive to its surface conditions. Factors like the presence of impurities, defects, or adsorb molecules can significantly influence its work function.
Generally, the work function of graphene is found to be in the range of 4.2 to 4.8 eV. This is relatively low compar to many other materials, making it suitable for applications that require efficient electron emission.
Implications of Low Work Function
Graphene’s low work function has several implications:
Field Emission:
It can emit electrons Special Database at relatively low appli voltages, making it useful for field emission displays and vacuum electronic devices.
Photoelectric Effect:
Graphene is highly sensitive to Email Material light, making it a promising material for photodetectors and solar cells.
Electronic Devices:
Its low work function can enhance the performance of electronic devices such as transistors and diodes.
