  5. Confusion with bandgap

    Closed | Responses: 0

    The default case shows a bandgap between the ground and the first excited states (less than 1 eV for GaAs!). This is confusing, since by bandgap students usually understand the difference...

  13. I compared a free electron in a 10nm x 10nm x 10nm closed box with an analytical formula and got a very different result

    Closed | Responses: 3

    I expect to get 0.011eV for the ground state quantization energy. The tool gives me 0.040eV.

    Is it a problem in my interpretation of the results or the tool is wrong?
