Hi everybody.
I had to simulate the i v characteristic of a SJ diode in siliconcarbide for the company where i work.
I want to see the characteristic iv when my device is in breakdown.
I will never used software Sentaurus and i would want to know if my file command is right to simulate the Breakdown of my device.
In the solve voice i did a sweep of voltage of anodo from 0 to -3000. I saved the graph to 0V and the graph to -3000V.
Then i load the solution with 0V and i swept the voltage of anodo from 0 to 20 to draw the characterstic in forward polarization.
Is this correct?!
Sorry for my bad english.
Bye Giovanni
