PHASE-SPACE SIMPLEX MONTE-CARLO FOR SEMICONDUCTOR TRANSPORT

We present a full band Monte Carlo algorithm based on phase-space simp lexes which has all of the advantages of analytical band Monte Carlo w hile preserving the accuracy of a full band structure. An adaptive, co ntour-aligned grid represents the energy band structure within the irr educible wedge to within an arbitrary tolerance. This discretization a llows exact treatment of the equations of motion and final state selec tion for a wide class of scattering mechanisms. Results using this met hod show at least an order of magnitude improvement in performance ove r previous full band codes.
