Dear all
I follow the trend used in Work_Fct example of espresso for obtaining the work function of my super cell. I increase the vaccum layer of my super cell and by PP.x save the V_bare + V_H potential and use average.x for averaging. But the macroscopic and planar averages is not match at the borders of supercell.(each of them converge to a different constant at the border) Could you help me that my results is true or not? and What is the diference between macroscopic and planar averages? Thanks indeed for your consideration Regards Meysam Pazoki SUT -------------- next part -------------- An HTML attachment was scrubbed...
