PDDOS calculation along y direction

[danial]

Dear Quantumwise developers;
 
I tried to calculate PDDOS, but the result is along Z direction, I need to investigate the alteration along Y axis of my device like the attached file.


I really appreciate you  in advance

could it be possible to help me?

I expect you used the ProjectedLocalDensityOfStetes analysis, which computes the local DOS for a range of energies, and plots the average DOS for each value of the z-coordinate. But you need to plot it along y instead. You can do this by manually creating the PLDOS plot as explained in a rather old tutorial: http://quantumwise.com/documents/tutorials/latest/MolecularDevice/index.html/chap.analysis.html#sect1.analysis.lddos.

You first need to compute the LDOS for all energies of interest (wr.t the Fermi level).
You then need to plot the results. Note the line "avg_z = numpy.apply_over_axes(numpy.mean,lddos[:,:,:],[0,1]).flatten()", which averages over the XY plane. There you probably need to use the indices "[0,2]" instead of "[0,1]" in order to average over the XZ plane.
