Identifying pitfalls when using the Miller–Abrahams rate in kinetic Monte Carlo simulations

Magdalena S. Dörfler, Heinz Bässler, Andrey Kadashchuk, Harald Oberhofer and Anna Köhler

The conventional Miller–Abrahams (MA) rate is a frequently applied rate for modeling the hopping transport of charges or excitons in organic semiconductors. However, the expression known as Miller–Abrahams rate is an approximation that has a more limited range of validity than the original, full expression. We study the effect of both rates in Kinetic Monte […]
