3D DDCC is named from three dimensional Drift-diffusion Charge Control solver. This is 3D finite element based Poisson and drift-diffusion solver developed by Dr. Yuh-Renn Wu. This solver initially developed with the 3D FEM thermal solver by Dr. Chi-kang Li when he was PhD student in Dr. Wu's group. Then the Poisson and drift-diffusion solver was added by Dr. Wu into this project. This solver was basically an expansion of 2D program into 3D program. Therefore, all new algorithm added in 2D program will be soon added into 3D program if no errors was found. The mesh algorithm was from Gmsh program. It also accept other mesh algorithm as long as it can be converged into gmsh format. The 3D FEM based Schrodinger eigen solver was also added. It also accept additional module to read in the optical field from 3D FD-TD program so that it can consider the solar cell problem. Then the 3D ray tracing program was developing. This solver now can solve many different problems such as trap problem, Gaussian shape tail state models, field dependent mobility, thermal, light extraction. Recently, 3D localization landscape model was also added into this program so that it can calculate the effective quantum potential very efficiently. This code is written with Fortran language.
