  1. I V characteristic ?

    Closed | Responses: 0

    First of thanking you very much for sharing this wonderful tool on PN junction. 

    I am using MATLAB for solving the same kind of configuration of PN junction and got the...

  2. Two functions in graphs?

    Closed | Responses: 1

    So when I’m running the simulations, on all of my graphs, I’m getting two functions. A red one, and a blue one. Which of these two functions is the proper one to use? For instance,...

  3. pn junction I-V curve

    Closed | Responses: 1

    For an ideal p-n junction, the Shockley equation applies and the I-V curve should be an exponential curve in forward bias. Why is it always linear in simulation?

    Though in 2D simulation,...

  4. Bias voltage parameter doesn’t work?

    Closed | Responses: 1

    No matter what parameter is entered for the bias voltage, the integrated potential is 0.6 volts.

    If it’s a bug, it’s a serious one.

    If it’s a feature …...

  5. Could you list the values of the material parameters you are using (GaAs, Si….)

  6. Useful for very high doping reverse bias conditions?

    Closed | Responses: 1

    I want to know how suitable this tool is for calculating IV characteristics for very high doped pn junctions into the 10(18) – 10(19) /cm3 under reverse bias conditions. It...

  7. PN Junction Lab – 100 Warnings

    Open | Responses: 1

    I had some trouble running PN Junction Lab; it gave more than 100 warnings for some simulation cases and then stopped. I think I figured it out: using exactly 1 or 2 V as applied voltage does...
