Quantized charge fractionalization at quantum Hall Y junctions in the disorder-dominated regime
Chaojing Lin, Masayuki Hashisaka, Takafumi Akiho +2
Fractionalization is a phenomenon where an elementary excitation partitions into several pieces. This picture explains non-trivial transport through a junction of one-dimensional e…
Energy gap tuning and gate-controlled topological phase transition in InAs/InGaSb composite quantum wells
H. Irie, T. Akiho, F. Couëdo +3
We report transport measurements of strained InAs/InGaSb composite quantum wells (CQWs) in the quantum spin Hall phase, focusing on the control of the energy gap thro…
Determination of -factor in InAs two-dimensional electron system by capacitance spectroscopy
Hiroshi Irie, Takafumi Akiho, Koji Muraki
We determine the effective -factor () of a two-dimensional electron gas (2DEG) using a new method based on capacitance spectroscopy. The capacitance-voltage profile of…
Impact of epitaxial strain on the topological-nontopological phase diagram and semimetallic behavior of InAs/GaSb composite quantum wells
H. Irie, T. Akiho, F. Couëdo +4
We study the influence of epitaxial strain on the electronic properties of InAs/GaSb composite quantum wells (CQWs), host structures for quantum spin Hall insulators, by transport…
