{"abstract":[{"text":"We report an electric-field-induced giant modulation of the hole g factor in SiGe nanocrystals. The observed effect is ascribed to a so-far overlooked contribution to the g factor that stems from the mixing between heavy- and light-hole wave functions. We show that the relative displacement between the confined heavy- and light-hole states, occurring upon application of the electric field, alters their mixing strength leading to a strong nonmonotonic modulation of the g factor.","lang":"eng"}],"intvolume":"       110","status":"public","author":[{"full_name":"Ares, Natalia","last_name":"Ares","first_name":"Natalia"},{"full_name":"Golovach, Vitaly N","last_name":"Golovach","first_name":"Vitaly"},{"id":"38DB5788-F248-11E8-B48F-1D18A9856A87","full_name":"Georgios Katsaros","last_name":"Katsaros","first_name":"Georgios"},{"last_name":"Stoffel","full_name":"Stoffel, Mathieu","first_name":"Mathieu"},{"last_name":"Fournel","full_name":"Fournel, Frank","first_name":"Frank"},{"last_name":"Glazman","full_name":"Glazman, Leonid I","first_name":"Leonid"},{"last_name":"Schmidt","full_name":"Schmidt, Oliver G","first_name":"Oliver"},{"first_name":"Silvano","last_name":"De Franceschi","full_name":"De Franceschi, Silvano"}],"publication_status":"published","_id":"1759","year":"2013","main_file_link":[{"url":"http://arxiv.org/abs/1208.0476","open_access":"1"}],"type":"journal_article","publist_id":"5365","date_published":"2013-01-23T00:00:00Z","publisher":"American Physical Society","oa":1,"date_created":"2018-12-11T11:53:51Z","volume":110,"doi":"10.1103/PhysRevLett.110.046602","month":"01","date_updated":"2021-01-12T06:53:01Z","issue":"4","title":"Nature of tunable hole g factors in quantum dots","publication":"Physical Review Letters","citation":{"apa":"Ares, N., Golovach, V., Katsaros, G., Stoffel, M., Fournel, F., Glazman, L., … De Franceschi, S.
