Dear all, I am new to Kwant and Python. I want to consider a contour plot of the conductance as a function of energy and the well depth for Tutorial 2.3.2. The contour plot is similar to the one on the homepage in “Conductance of a Corbino disk in a quantum Hall regime”, but the codes are not shown in the tutorials. I want to learn this example since it will be more flexible to consider the effects of the device parameters. I want to output the results into a .txt file with the energy in the first column, well depths in the second column, conductance in the third column, so I can plot the contour by origin. Tutorial 2.3.2 is a simple example to consider the contour plot, and we may only need to do small changes. The codes for Tutorial 2.3.2 areattached. Could you help me? Thanks in advance. Kwok-Long Lee
