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...

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?
