Abstract
We present here the results of photocurrent from boron pnictides namely BP. The photocurrent in this system had been calculated by using three types of potential namely free- electron, Kronig-Penney and Muffin-Tin potentials. Schrodingers’ equation has been solved by using these potentials to obtain the necessary initial and final state wave-functions for the electrons. These wave-functions are used for evaluating the matrix element ⟨ Ψf\\p.A + Ap\\Ψi⟩ which is involved in the formula of photocurrent.
