Charge carrier density simulation
WebA fast initial photoluminescence (PL) decay component observed after pulsed photogeneration is demonstrated to result from rapid localization of free charge carriers in unoccupied trap states, which may be followed by de-trapping, or nonradiative recombination with free carriers of opposite charge. WebTotal Charge in Transition Region To solve for the electric fields, we need to write down the charge density in the transition region: In the p-side of the junction, there are very few electrons and only acceptors: Since the hole concentration is decreasing on the p-side, the net charge is negative: ρ0 (x) =q(p0 −n0 +Nd −Na) ρ0 (x) ≈q ...
