We developed a number of methods targeted at fast full-band mobility calculation of device channels, including: subband structure calculation, determination of couplings in k-space, and evaluation of the transition rates based on our recent modeling efforts of SRS. The entire workflow is implemented within the Vienna Schrödinger-Poisson (VSP) simulation framework. Every step in the process is parallelized with close-to-linear scalability. The resulting performance boost brings full-band mobility modeling one significant step closer tornmainstream TCAD device simulation.
