(For MAC & Linux Users, if you have Matlab installed you can also download this windows version. Execute ddcc_1d.m in Matlab command terminal. (video tutorial to used ddcc in linux)

(For the zip file version, please extract the zip file in the folder. Install MCR first and find the file “ddcc_1d.exe” and execute it.

Windows version is Compiled with Matlab 2017b. 64 bit 2017b MCR link here

Release Note: 4.71 version 03/11/2023
  •      Add new functions for the effective mass of different directions for the Schrodinger solver, and landscape solver.
  •    The explanation of the new function in affective mass, band shift can be found in the manual here
  •    1D can now use affinity to align the band offset. This is easier for the case where the bandgap is the same, but the electron affinity is not the same.
  •   Electron 2nd valley is added to the program for consideration of X/L valley in III-V materials. This feature goes with the landscape where the landscape can add solve Ec Ec_2nd, Ev_lst(hh), Ev_st (LH). In addition, HH and LH do not need to be Ev. It can have additional shifts to the Ev. The Ec and Ec2 do not need to be Ec also. Note, the energy shift of Ec and Ev does not need to couple with the landscape solver.
  • Note this is a new add-in function to couple with the landscape solver. Hence, please come back to check if any bugs was found after this version was released.
