  1. effective mass

    Closed | Responses: 8

    I was simulating a rectangular nanowire with the default parameters. It generated extremely small (0.0001) effective masses for band 1 valley 1. Please have a look. Also, we need to have the...

  2. 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...

  4. Uniaxial Strain Simulation not as specified

    Closed | Responses: 2

    I tried to some simple uniaxial strain simulation for bulk. The problem that I encountered is that even though I specified the initial and final strain, the strain value in the final results is...
