  1. 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 …

  8. bulk bandstructure: k-axis scale

    Open | Responses: 2

    It seems that the bulk bandstructure shows E-k along L->Gamma->X->UK->Gamma. If so, the k-scale does not seem to be correct. The distance between Gamma and X appear to be correct (2pi/a0), but the …

  14. Could k be expressed by kx ky kz?

    Open | Responses: 2

    I do not really know the meaning of "effective k" in the result figure.(the square root of kx ky kz?) This tool can show a table of k-E. Is this possible to show the "kx ky kz E" in the final result …

  15. 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* …

  20. Followup: Uniaxial Strain is Scaled from Entered Value

    Open | Responses: 1

    So I've kind of answered my own question: I can see that the strains are applied along the z-axis even though the program states along (Exx). So when I ask the program to apply a 0.01 strain along …
