2. effective mass

   Q&A|Closed | Responses: 9

   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...

4. Followup: Uniaxial Strain is Scaled from Entered Value

   Q&A|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...
