Its applicability is demonstrated for anion vacancies at the (110) surfaces of III–V semiconductors. We find the (+/0) charge-transition level to be 0.49 eV above the surface valence-band maximum for GaAs(110) and 0.82 eV for InP(110). The results show a clear improvement over the local-density approximation and agree closely with an experimental analysis."}],"file":[{"content_type":"application/pdf","creator":"schindlm","file_name":"PhysRevLett.97.226401.pdf","file_size":122754,"relation":"main_file","date_created":"2020-08-28T18:04:00Z","date_updated":"2020-08-30T15:54:01Z","access_level":"open_access","file_id":"18598","description":"Creative Commons Attribution 3.0 Unported Public License (CC BY 3.0)","title":"Quasiparticle corrections to the electronic properties of anion vacancies at GaAs(110) and InP(110)"}],"license":"https://creativecommons.org/licenses/by/3.0/","publication":"Physical Review Letters","title":"Quasiparticle corrections to the electronic properties of anion vacancies at GaAs(110) and InP(110)","publisher":"American Physical Society","date_created":"2020-08-28T18:02:16Z","year":"2006","quality_controlled":"1","issue":"22"},{"oa":"1","date_updated":"2022-11-11T06:59:10Z","author":[{"first_name":"Arno","id":"458","full_name":"Schindlmayr, Arno","last_name":"Schindlmayr","orcid":"0000-0002-4855-071X"},{"full_name":"Godby, Rex William","last_name":"Godby","first_name":"Rex William"}],"volume":80,"doi":"10.1103/PhysRevLett.80.1702","publication_status":"published","has_accepted_license":"1","publication_identifier":{"issn":["0031-9007"],"eissn":["1079-7114"]},"citation":{"ama":"Schindlmayr A, Godby RW.
