  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...

  8. biaxial strain in bulk produces no results

    Open | Responses: 3

    Starting from scratch with a new simulation I am just turning on bi-axial strain in the bulk simulation mode and I get not simulation results.


  9. 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...

    Dear Admins, I am interested in calculating the effective mass along the confinement direction for nanowire geometries. Can this be done using Bandstrlab or is there another tool for it? Thanks...


  16. 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...


  17. 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...
