A single-electron device and circuit simulator with a new algorithm to incorporate co-tunneling

A multipurpose single-electron device and circuit simulator is presented, with which it is possible to simulate a wide variety of single-electron devices. the simulator features among others the incorporation of co-tunneling by two different simulation methods, a graphical user interface and a graphical circuit editor. A new algorithm for the simulation of very rare events, where a Monte Carlo method is combined with a direct calculation, is outlined in detail.
