(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A p+-n junction with the n-side donor concentration of 10^{16}cm^{-3}. If n_{i}= 10^{10}cm^{-3}, the relative dielectric constant e_{r}= 12, D_{n}= 50cm^{2}/s, D_{p}= 20cm^{2}/s, t_{n}= 100ns, t_{p}= 50ns. Calculate the hole diffusion current density 2mm from the depletion edge on the n-side under a forward bias of 0.6V.

2. Relevant equations

J(p) [drift] = -qD_{p}Δp

3. The attempt at a solution

My only understanding of how to solve this problem is by the relevant equation given above, yet i dont know how to find Δp from the given information. Perhaps there is another equation that suites better in solving this problem given the parameters at hand.
