Here we focus on such heavy-hole states confined in germanium hut wires. By tuning the growth density of the latter we can realize a T-like structure between two neighboring wires. Such a structure allows the realization of a charge sensor, which is electrostatically and tunnel coupled to a quantum dot, with charge-transfer signals as high as 0.3 e. By integrating the T-like structure into a radiofrequency reflectometry setup, single-shot measurements allowing the extraction of hole tunneling times are performed. The extracted tunneling times of less than 10 μs are attributed to the small effective mass of Ge heavy-hole states and pave the way toward projective spin readout measurements."}],"language":[{"iso":"eng"}],"related_material":{"record":[{"id":"7977","relation":"popular_science"},{"status":"public","relation":"dissertation_contains","id":"69"},{"id":"7996","status":"public","relation":"dissertation_contains"}]},"date_updated":"2023-09-26T15:50:22Z","publisher":"American Chemical Society","author":[{"orcid":"0000-0003-2424-8636","last_name":"Vukusic","id":"31E9F056-F248-11E8-B48F-1D18A9856A87","first_name":"Lada","full_name":"Vukusic, Lada"},{"last_name":"Kukucka","id":"3F5D8856-F248-11E8-B48F-1D18A9856A87","full_name":"Kukucka, Josip","first_name":"Josip"},{"id":"35DF8E50-F248-11E8-B48F-1D18A9856A87","first_name":"Hannes","full_name":"Watzinger, Hannes","last_name":"Watzinger"},{"first_name":"Georgios","full_name":"Katsaros, Georgios","id":"38DB5788-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8342-202X","last_name":"Katsaros"}],"scopus_import":"1","intvolume":"        17","department":[{"_id":"GeKa"}],"ddc":["539"],"_id":"840","doi":"10.1021/acs.nanolett.7b02627","date_created":"2018-12-11T11:48:47Z","file_date_updated":"2020-07-14T12:48:13Z","external_id":{"isi":["000411043500078"]},"publication":"Nano Letters","citation":{"apa":"Vukušić, L., Kukucka, J., Watzinger, H., &#38; Katsaros, G.
