Application of Fractional Operators in Modelling for Charge Carrier Transport in Amorphous Semiconductor with Multiple Trapping

This paper is devoted to investigate the description of fractional space and time, mathematical modelling of charge carrier transport in disordered semiconductor. We propose the analytical approximate solutions of fractional drift diffusive equation that is under the influence of multiple trapping, by employing numerical technique the fractional reduced differential transform method (FRDTM). The present work gives wider description of FRDTM and provides approximate results in terms of convergent series. The approximate results through FRDTM, rendering that the proposed method is very simple, effective and reliable in use and may easily be applicable for solution of more general, non-linear fractional differential equations.
