  2. Plotting a 6 barrier device

    Closed | Responses: 0

    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.

  3. Sweeping the bias back and forth

    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...

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

    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...

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

    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...
