Band Gap value

Closed | Responses: 1

For the default simple quantum dot, the bulk band gap is given as 1.43 eV (GaAs), and the value of Eg for the quantum dot is given as 0.18 eV. This is also the energy of the absorption...

Where did spheroidal geometry go?

Closed | Responses: 2

In the introductory material, a spheroid is one of the options for geometry. It appears that this is not longer an option in the current version, is there a reason for that?

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...
