WebThe COHP tool extracts the important chemical information and makes it available at one glance! While COHP analysis has been restricted to local-orbital band-structure codes (such as TB-LMTO-ASA) in the past, it is possible to project COHP (and also COOP) information from plane-wave DFT data. This has been accomplished between 2011 and … WebJun 2, 2011 · In this paper, we describe a way to re-extract Hamilton-weighted populations from plane-wave electronic-structure calculations to develop a tool analogous to the familiar crystal orbital Hamilton population (COHP) method.
