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

Abstract

The spatial variation of the hole current injected into n-type material was determined by using the current density due to hole diffusion J_h 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 eμ_hN_hE 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.
