Title: Questions on Local density of states(LDOS)
Post by: kaypu on October 1, 2012, 03:50

Dear QW team:
    i read a paper PRL 99, 146802 (2007) some days before, i've a question on Fig.5(e). They have obtained the LDOS in the energy window [0.5 eV, 0.5 eV], but as far as i know, in atk, we can only plot LDOS in a centain energy (for example:Ef). I want to know how to plot LDOS in a energy window.

thanks
kay

A straightforward way: 1) divide the energy range into several points uniformly (the number of energy points depending on the required accuracy), 2) calculate the LDOS for every energy point; 3) sum up all the LDOSs.
