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...
