Research Abstract

In this research program, a development of highly efficient cold cathode has been performed utilizing pn junction of diamond focusing on the negative electron affinity nature. The electron emission efficiency of 7.5% was achieved from diamond pn junction cold cathode with excellent stability over time. The energy of emitted electron was about 4.1 eV above the Fermi level of p-type diamond and it convinces that the electron transported through pn junction interface into p-type diamond drifts through conduction band and emitted into vacuum easily with the help of negative electron affinity nature.
