{"oa":"1","abstract":[{"lang":"eng","text":"A quantum dot molecule doped with a single electron in the presence of diagonal and off-diagonal carrierphonon\r\ncouplings is studied by means of a nonperturbative quantum kinetic theory. The interaction with acoustic phonons by deformation potential and piezoelectric coupling is taken into account. We show that the phonon-mediated relaxation is fast on a picosecond time scale and is dominated by the usually neglected off-diagonal coupling to the lattice degrees of freedom leading to phonon-assisted electron tunneling. We show that in the parameter regime of current electrical and optical experiments, the microscopic non-Markovian theory has to be employed."}],"has_accepted_license":"1","date_created":"2018-08-28T08:57:24Z","keyword":["tet_topic_qd"],"file_date_updated":"2018-09-04T19:58:41Z","publication_status":"published","issue":"11","ddc":["530"],"file":[{"date_updated":"2018-09-04T19:58:41Z","date_created":"2018-08-28T08:58:21Z","creator":"hclaudia","file_size":680408,"access_level":"open_access","content_type":"application/pdf","relation":"main_file","file_id":"4175","file_name":"2010 Grodecka-Grad,Förstner_Theory of phonon-mediated relaxation in doped quantum dot molecules.pdf"}],"article_number":"115305","doi":"10.1103/physrevb.81.115305","publisher":"American Physical Society (APS)","author":[{"first_name":"A.","last_name":"Grodecka-Grad","full_name":"Grodecka-Grad, A."},{"first_name":"Jens","orcid":"0000-0001-7059-9862","full_name":"Förstner, Jens","id":"158","last_name":"Förstner"}],"status":"public","intvolume":"        81","year":"2010","user_id":"158","citation":{"ieee":"A.
