Title: Comparing two plots
Post by: m.ghashghayi on February 3, 2016, 12:33

Hello
I want to compare two I-V Curves on one plot.what do i do ?

One option is to use a script for plotting the IV curves (see attachments).

Thanks for your kindly answer
I have a  question again.I want to extract data for I-V plot according to V gate (x = vgate , y=Current and lables = Vbias) , what do I do ?

Please check out the section "Performing a gate scan" in this tutorial: http://quantumwise.com/documents/tutorials/latest/NanowireDevice/index.html/chap.nanowiredevice.html#sect1.nanowiredevice.job (http://quantumwise.com/documents/tutorials/latest/NanowireDevice/index.html/chap.nanowiredevice.html#sect1.nanowiredevice.job)

You essentially need to write a script that loops over the desired gate voltages and sets them on the configuration, calculates the transmission spectrum every time, and saves the transmission spectra to a single file.
