IVCurve and IVCharacteristics
« on: February 3, 2025, 12:01 »
Hello,

I am using the IVCurve class for calculating an IV curve from -1 V to 1 V with step of 100 mV. I would like to understand how these calculations work. Here is what I believe is the step by step:

1. Do a self-consistent calculation for zero-bias
2. Do a self-consistent calculation at 100 mV reading the zero-bias
3. Do a self-consistent calculation at 200 mV reading the device configuration of 100 mV
4. And so on...
5. Do a transmission calculation for each self-consistent calculation already done.

However for negative bias I do not know if is the same procedure or for each negative bias, for example -100 mV, is reading the device configuration of the correspondent positive bias, i.e. 100 mV.

Is the procedure the same for IVCharacteristics class?

Hello, the calculation of negative bias voltage is similar. ATK will read 0V and then calculate -0.1V. It will read 0V&-0.1V and calculate 0.2V and keep calculating.

Thank you. However it is really using more than one previous bias calculation? I am not sure sure of that...
