Licence key requested Form:Release Note:
2D: 1.6.1: Major update. additional functions: (1) more impact ionization models. (2) Generation profile model, (3) functional doping profile model, (4) more manual, (5) Random alloy fluctuation model are all added. Add SiC, Ga2O3, and HfO material into the database.
2D: 1.5.7: Update the kernel of 2D-ddcc-win64.exe and raytracing-win64.exe. Adding a database of new materials.
2D: 1.3.5: Update the kernel of 2D-ddcc-win64.exe and raytracing-win64.exe (not sync to the newest updated version when packaging releases). Fixed minor bugs in ray tracing with gmsh. Fixed bugs in RCWA, raytracing data saving,g and reloading.
2D: 1.2.9: Fixed bugs. Fixed RCWA TM’s code error. And improve the TM emission codes to sparse matrix solver to make speed enhancement. The speed could be 1000X faster with a smaller memory.
2D: 1.2.3: Add multi-valley simulation of 2nd electron bands. Include the deformation potential. Fixed RCWA error. Improve the copy-paste function, remove, and move up & down functions.
2D: 0.23.1: Add SiC material parameters. Fix the voltage step limitation from 15V to a larger value. Note: Large voltage needs a fine mesh.
