Accurate Monte Carlo modeling of terminal currents in short semiconductor devices by using a generalized Ramo-Shockley theorem

The authors present an efficient and simple method using a generalized formulation of the Ramo-Shockley theorem for the calculation of the time-dependent terminal currents in multi-port devices within the ensemble Monte Carlo modeling, including the displacement current and the separate contribution of each particle type. Moreover, our technique is optimized for the cloud-in-cell and box integration framework. We emphasize that our formulation does not require any additional optimization theory, is easy to implement and does not increase CPU time consumption.
