  3. 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 improve …

  4. L point on bulk central bands and bulk (all) band structure plots appears truncated

    Closed | Responses: 0

    When simulating the bulk band structure for GaAs and Si (I haven't tried others), I noticed that the L point appears to be truncated on the plots. If I use an earlier version of the tool (1.x) I see …

  5. The results for strained Si nanowire are different with the other literature

    Closed | Responses: 0

    Hello, The obtained results for strained silicon nanowire are different with other literature. The energy difference between the minimum of light and heavy bands should be decreased in presence …

  11. No output for self-consistent calculation

    Closed | Responses: 0

    Hi, 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 correctly. I …

  12. 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 sp3s* …
