Abstract

Abstract: Device design in nano-electronics typically leads to large multi-physics problems in time-domain that are characterised by strong feedback coupling. The classical monolithic method results in huge linear systems that must be solved for all time steps. In this contribution a fractional time-stepping scheme is employed in the context of electro-thermal problems in nano-electronics that solves the system without sacrificing the convergence order in time.
