Here, we study holes confined in Ge hut wires, a so-far unexplored type of nanostructure. Low-temperature magnetotransport measurements reveal a large anisotropy between the in-plane and out-of-plane g-factors of up to 18. Numerical simulations verify that this large anisotropy originates from a confined wave function of heavy-hole character. A light-hole admixture of less than 1% is estimated for the states of lowest energy, leading to a surprisingly large reduction of the out-of-plane g-factors compared with those for pure heavy holes. Given this tiny light-hole contribution, the spin lifetimes are expected to be very long, even in isotopically nonpurified samples.","lang":"eng"}],"status":"public","department":[{"_id":"GeKa"}],"publist_id":"5941","type":"journal_article","ddc":["539"],"has_accepted_license":"1","volume":16,"scopus_import":1,"project":[{"call_identifier":"FP7","_id":"25517E86-B435-11E9-9278-68D0E5697425","name":"Towards Spin qubits and Majorana fermions in Germanium selfassembled hut-wires","grant_number":"335497"}],"publication":"Nano Letters","page":"6879 - 6885","tmp":{"short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"citation":{"ieee":"H.
