High mobility holes at germanane/Ge(111) allotropic cross-dimensional heterointerface

Yumiko Katayama, Daiki Kobayashi, Hikaru Okuma +3

Germanane (GeH) is essentially a hydrogen-terminated Ge analog of graphene with a direct gap (~1.6 eV). Record hole mobility mu_h~67,000 cm2/Vs is found at 15 K for a single allotr…

Large Rashba spin-orbit coupling in metallic SrTaO $_{3}$ thin films

Hikaru Okuma, Yumiko Katayama, Fukunobu Kadowaki +2

Epitaxial thin films of SrTaO $_{3}$ with thickness ( $t$ ) smaller than 74 nm were successfully fabricated on an insulator (LaAlO $_{3}$ ) $_{0.3}$ (Sr $_{2}$ AlTaO $_{6}$ ) $_{0.7}$ substrate. Films…
