Abstract

We present here a model calculation of photoassisted field emission current (PFEC) from tungsten. Transfer Hamiltonian method was used for calculating the transition probability. Matrix element for the transition probability was calculated by using the wavefunctions which are deduced by applying the Kronig-Penney potential model.
