Mott−schottky effect

Nettet14. apr. 2024 · Finally, we convert nominal dopant concentration, that is the concentration as calculated by taking the volume ratios between the polymer and dopant solutions, to carrier concentration N d, using Mott–Schottky analysis (see supplementary material Figs. 3 and 4 for the plots of C −2 against DC bias). NettetThe next problem is the frequent assumption that U − U FB ≈ Δ ϕ SC (); hence Mott–Schottky graphs in Fig. 2 are often simply plotted versus U, such that U FB can be determined by extrapolation. However, this assumption is not always justifiable. If C H is known, it is possible to predict the distribution of applied potential between …
