O In ambipolar transport mechanism, both electrons and holes transport with same effective mobility. O Efective mobility and diffusion coefficients do not depend on the carrier concentrations. Under low injection, the effective diffusion coefficients are that of majority carrier. O Minority carrier lifetime is essentialy a constant under low injection.

Picture attached of question The 1D Poisson equation for the calculation of electrostatic potential can be written as: ?2?(?) ??2 = − ? ?(?) ???0 where q is the change of electron, N is the total charge density, and ε is material permittivity which consists of the relative permittivity εr and the permittivity of a vacuum ε0. Solve the above equation and find the potential for a p-n junction assuming the depletion approximation, i.e., when a concentration of acceptors NA is much larger than a concentration of donors ND so that: ?? ≫ ?? and this lead to ?? ≫ ??.

Since there is a charge density of 100 nc / m on the 2 m radius quadrant in the second region, the differential charge taken from a random point and the corresponding ground vector have been correctly defined. Define additionally the location (R) of the point whose potential is desired to be found and the amount of differential change dV in the voltage that will occur due to the differential load you selected.
We consider a half-infinite bar of p-type silicon, as shown in the figure below, with a "minority carrier digester" at (x=0), such that the electron concentration, np, at this location is zero (i.e., np(x=0)=0). This bar is uniformly illuminated and as a result carriers are generated at a rate g′. The electric field in the bar is zero and we consider a steady-state situation. The expression for the excess minority carrier concentration as a function of x is given by:
