SURFACE: Electronic surface states analysis program A post-processing tool for Abinit density functional theory slab calculations to automate extraction and indentification of electronic surface states. It generates charge/probability density profiles that are analyzed in the context of their spatial localization. The program produces color-coded band structures. For details, please see the README file in the program repository below.
