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…

Ultrafast Time-Resolved Faraday Rotation in EuO Thin Films
F. Liu, T. Makino, T. Yamazaki +5
We have investigated the ultrafast spin dynamics in EuO thin films by time-resolved Faraday rotation spectroscopy. The photoinduced magnetization is found to be increased in a tran…
