Title The EVEREST solver module : version 4.0
Abstract In this report we describe version 4.0 of the EVEREST solver module which forms part of the EVEREST semiconductor device modelling suite of programs. The solution module solves the semiconductor device equations in steady state or transient mode in three dimensions. The continuous equations are spatially discretised by the control region method on a mixed mesh of tetrahedral and hexahedral elements. The temporal discretisation of the continuity equations is performed by the variable order, variable time step Gear method. The nonlinear and the linear systems of equations are solved using damped Newton with correction transformation and incomplete Choleski conjugate gradient squared methods with Eisenstat's preconditioning. For physical models, the user has the choice of several mobility models namely; lattice, impurity concentration dependent and field dependent. Recombination rate can be either zero or a combination of Shockley-Read-Hall and Auger. The effects of bandgap narrowing due to heavy doping may also be modelled. Surface charge layers may be specified within the device. Transient simulation allows a choice of functions to define the bias variation on the contacts.
