Determination of the Spatial Variation of the Hole Current Injected into N-Type Material, in ID.

DU Onah, BN Osonwa, JE Ekpe


The spatial variation of the hole current injected into n-type material was determined by using the current density due to hole diffusion Jh and the current of a positive charge q moving with a velocity v at an electric field E in the continuity equation. The boundary condition imposed in using these equations was that the conduction current density hNhE was neglected in comparison with the diffusion current due to holes. Method of separation of variables was also incorporated in the solution and the hole current in n-type material in ID was determined.

Keywords: hole current, n-type material, continuity equation and separation of variables.
