Flexible object-oriented device simulation using encapsulated scattering tables

One of the largest problems with most device simulators is their lack of flexibility. This lack is generally caused by brittle code that makes simulating new types of devices difficult. To address this problem, we have written a device simulator with a dedicated object-oriented design that stresses flexibility and allows novel device geometries and configurations to be specified with ease. This adaptability was accomplished by following a strict design approach in which interface was separated from implementation as much as possible. In particular, we have developed code for a Mesh object that simplifies setting up devices with complicated material structures and doping regions. As such, it allows us to model new devices more easily than conventional device simulator packages.
