  4. calculation of semiclassical profile for using generalized green's function approach

    Q&A|Open | Responses: 1

    For solving Equilibrium and Non-Equilibrium green's function , the semiclassical profile is calculated with thomas-fermi charge. How is the fermi level defined for calculation of charge in...

    Q&A|Closed | Responses: 7

    Hi guys,

    really impressed by your work here. I was wondering: is possible to replicate these type of simulations in TCAD Sentaurus?

    Hope you can reply

  7. Plotting a 6 barrier device

    Q&A|Closed | Responses: 1

    When I try to use 6 barrier device with default settings, I don’t get any of the plots. It gives me a Rappture error.


  8. Sweeping the bias back and forth

    Q&A|Closed | Responses: 0

    I wanted to check the hysteresis in current that occurs in the NDR region of the I-V curve, when you sweep the bias forward and then back again, due to redistribution of charges. However, I...


  9. Shows absolute current-voltage characteristics. Whats the area?

    Q&A|Open | Responses: 3


    The latest version of the tool outputs absolute current-voltage curve, rather than earlier current density-voltage curve. What is the area that ie being used to calculate absolute...

  14. quantum mechanical charge appears to be over-estimated by a factor of 5.7

    Q&A|Open | Responses: 1

    Comparing the semiclassical charge for a long, highly doped contact to the single pass quantum mechanical charge appears to result in charge that is about a factor 5.7 to high. This must be a...
