Researchers study the effects of defects on electron emission of Graphene electrodes

Researchers from the Chinese Academy of Sciences, the University of Science and Technology of China and North China University of Water Resources and Electric Power have studied the effects of irradiation defects on the work function of graphene electrodes in thermionic energy converters (TECs) and found that the generation of defects in graphene through irradiation would increase the work function and reduce the electron emission capacity.
