Shubnikov-de Haas quantum oscilations reveal a reconstructed Fermi surface near optimal doping in a thin film of the cuprate superconductor PrCeCuO
Nicholas P. Breznay, Ian M. Hayes, B. J. Ramshaw +6
We study magnetotransport properties of the electron-doped superconductor PrCeCuO with = 0.14 in magnetic fields up to 92~T, and observe Shubnikov de-Haas…
Engineering quantum spin Hall insulators by strained-layer heterostructures
Takafumi Akiho, François Couëdo, Hiroshi Irie +3
Quantum spin Hall insulators (QSHIs), also known as two-dimensional topological insulators, have emerged as an unconventional class of quantum states with insulating bulk and condu…
Single-edge transport in an InAs/GaSb quantum spin Hall insulator
François Couëdo, Hiroshi Irie, Kyoichi Suzuki +2
We report transport measurements in a single edge channel of an InAs/GaSb quantum spin Hall insulator, where the conduction occurs through only one pair of counterpropagating edge…
Evaluation of Disorder Introduced by Electrolyte Gating through Transport Measurements in Graphene
Andrew Browning, Norio Kumada, Yoshiaki Sekine +3
We evaluate the degree of disorder in electrolyte gating devices through the transport measurements in graphene. By comparing the mobility in ion- and standard metal-gated devices,…
Andreev reflection and bound state formation in a ballistic two-dimensional electron gas probed by a quantum point contact
Hiroshi Irie, Clemens Todt, Norio Kumada +4
We study coherent transport and bound-state formation of Bogoliubov quasiparticles in a high-mobility InGaAs two-dimensional electron gas (2DEG) coupled to a sup…
