  9. 2% biaxial strain Ge, promen at the Gamma point

    Closed | Responses: 0

    Dear all, When I simulate the bandstructure of Ge with high strain (2%), I get a discontinuity at the Gamma point, and therefore the effective masses are not correctly calculated. Can you...

    I ran the tool for self-consistent calculation but I didn’t obtain any result. It seems the tool does not work for this type of job. However, for non-self-consistent it works...


  18. differences between sp3s* and sp3d5s* models

    Closed | Responses: 1

    In this version of bandstrlab, the sp3s* model is not implemented (there is only one model, i.e. the sp3d5s*). It would be interesting to have that model to compare the differences between the...
