Title: how to plot position-dependent density of states
Post by: kaypu on October 25, 2012, 14:44

Dear QuantumWise staff:

i've read a paper PRL 95,206805, there is a beautiful pic of position-dependent density of states shown in fig. Can atk do it? how to do? need some script?

Regards

This is just the LocalDensityOfStates in ATK. You can insert it from Analysis in the Script Generator and then plot the result in the Viewer as a contour plot, like the picture.

it is to say that i must calculate a series of LDOS at different energy, and plus them? is that right?

We have a tutorial that calculates such a plot, see
