Parameter-free many-electron self-energy corrections to DFT Kohn–Sham eigenvalues are demonstrated to lead to excellent agreement with experiments at finite bias, improving upon order-of-magnitude errors in currents obtained with standard DFT approaches. We further propose an approximate route for prediction of quantitative IV characteristics for both symmetric and asymmetric molecular junctions based on linear response theory and knowledge of the Stark shifts of junction resonance energies. Our work demonstrates that a quantitative, computationally inexpensive description of coherent transport in molecular junctions is readily achievable, enabling new understanding and control of charge transport properties of molecular-scale interfaces at large bias voltages.","lang":"eng"}],"language":[{"iso":"eng"}],"type":"journal_article","scopus_import":"1","status":"public","volume":12,"page":"6250-6254","OA_type":"green","article_processing_charge":"No","year":"2012","doi":"10.1021/nl3033137","arxiv":1,"quality_controlled":"1","external_id":{"arxiv":["1212.0019"]},"OA_place":"repository","day":"20","oa":1,"publication_status":"published","intvolume":"        12","_id":"18002","extern":"1","title":"Quantitative current–voltage characteristics in molecular junctions from first principles","author":[{"last_name":"Darancet","full_name":"Darancet, Pierre","first_name":"Pierre"},{"full_name":"Widawsky, Jonathan R.","first_name":"Jonathan R.","last_name":"Widawsky"},{"first_name":"Hyoung Joon","full_name":"Choi, Hyoung Joon","last_name":"Choi"},{"first_name":"Latha","full_name":"Venkataraman, Latha","id":"9ebb78a5-cc0d-11ee-8322-fae086a32caf","orcid":"0000-0002-6957-6089","last_name":"Venkataraman"},{"full_name":"Neaton, Jeffrey B.","first_name":"Jeffrey B.","last_name":"Neaton"}],"oa_version":"Preprint","month":"11"}
