  6. 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...

    Closed | Responses: 0

    When simulating the bulk band structure for GaAs and Si (I haven’t tried others), I noticed that the L...

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

    Closed | Responses: 0


    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...

  9. Self Consistent for Ge DGMOS

    Closed | Responses: 0

    I am currently trying to simulate the Band structure for a Ge DGMOS (with thickness 4nm) using self consistent calculation at a particular Bias Voltage. However the simulator is unable to...

    Is it possible to calculate band structure at different temp?

  14. No output for self-consistent calculation

    Closed | Responses: 0


    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...

  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...

  16. Strain Tight-Binding model

    Closed | Responses: 0

    I would like to know how this tool accounts the strain in TB Hamiltonian. Does it alter both the on-site and off diagonals elements? I would truly appreciate if you could help me out.

  17. Bulk Si eff. mass vs. biaxial Strain

    Closed | Responses: 2

    Hello there,

    I was simulating Strain sweep on Bulk Si. I applied biaxial strain from -0.015 to 0.015 in

  18. No Output

    Closed | Responses: 1

    Hi there,

    It seems that the tool is not working…I was able to get some output couple of hours back but now it shows only a bunch of log files everytime I simulate anything. Tried...
