1. what does the tool improvement of version 1.1.9 really mean?

   Open | Responses: 1

   1.1.9 - A problem pertaining to the geometry adjustment when a tight-binding calculation is called, has been corrected. i think a bit more description is really needed. Is the barrier …

2. the lattice constant for tight binding should be really used in the generation of the heterostructure

   Open | Responses: 2

   Right now the lattice constant is set to the GaAs lattice constant of 0.56. That means that the barriers should be automatically set to equal multiples of that lattice constant - one cannot have a …

3. Effective mass variation in pcpbt is not working correctly for tight binding

   Open | Responses: 2

   For a double barrier structure doubling the barrier height or doubling the effective mass should roughly have the same effect (for low lying energy states, say when the barrier is already high and …

4. the tight binding calculations do not yet allow for a change in effective masses

   Open | Responses: 3

   It would be great if the tool would also allow for changing effective masses along the device. Barrier materials have typically different effective masses from well materials. It would also be …

5. single barrier choice results in no output

   Open | Responses: 1

   I thought this had gotten fixed in the code, but again the tool does not create any outputs when a single barrier is chosen
