We have shown here the results of PFEC (photofield emission current) calculated for GaAs (gallium arsenide). We have used the initial state wavefunctions derived using the Kronig-Penney potential model for evaluating the PFEC. We have found that PFEC is not oscillatory as obtained by Modinos and Klient, [Solid State Commun. 50, 651 (1984)], but it is an exponential function.
