【 摘 要 】

In this report, we have shown the variation of photofield emission current as a function of applied electric field, the photon energy and initial state energy of the electrons with reference to the Fermi level. The photofield emission current is calculated with the help of Kronig- Penney model potential. The origin of peak in photofield emission current in the valence band is explained with the help of result of density of state calculated.
