Hi, I am trying to simulate STM images for few systems. I was successful in reproducing exactly experimental image. But I doubt if I understand the tag heightmax and heightmin in INPUTPP. I am appending the input pp description given in the code below. I would like to understand the physical meaning of these tags for experimental STM tip. It says that height min should be somewhere in the bulk, does that mean the STM tip goes deep inside the material?
============================================================= heightmin ! (real) minimum value of the plane in which searching for the isosurface ! ! default value -> 0.0d0 ! heightmax ! (real) maximum value of the plane in which searching for the isosurface ! ! default value -> 1.0d0 ! ! the two parameters above are in percentage with respect to the ! ! height of the cell, i.e. between 0.0 and 1.0. ! ! If heightmax < heightmin, it treats it as if it's in the ! ! upper periodically repeated slab. ! ! Put heightmin somewhere in the bulk and heightmax in the vacuum ============================================================ Summayya Kouser Postdoctoral Researcher, Rice University, USA
