Dear all, I have been trying to find the simulated STM images for some surfaces. I have some doubts about the procedure:
1) The option of 'stm_wfc_matching' is not working. According to some forum posts, it has been disabled for some latest versions. The working of that option itself was not very clear to me from documentation, but why was that disabled? And if necessary, can I use the wave-functions and charge density files from the latest version for the older version post-processing tools, to get this option working? 2) I am interested to know that because from calculations what we get is ILDOS and we plot it some fixed plane. This will correspond to "constant-height" mode of the STM experiments. However, more common mode in experiments is "constant-current"; and that wave-function matching option has some z and dz parameters which probably were used to get the image corresponding to the latter mode. Is that correct guess? 3) I have seen some papers which give simulated STM images calculated at "constant-current" mode using QE (e.g. - Valentin, JCP 2007). So does there exist some post-processing tool to calculate that? If yes, where can I find it? Thanks and regards, Madhura. -- Madhura Marathe, PhD student, TSU, JNCASR, Bangalore. India.
