Quantized Majorana conductance
Hao Zhang, Chun-Xiao Liu, Sasa Gazibegovic +19
Majorana zero-modes hold great promise for topological quantum computing. Tunnelling spectroscopy in electrical transport is the primary tool to identify the presence of Majorana z…
Materials considerations for forming the topological insulator phase in InAs/GaSb heterostructures
Borzoyeh Shojaei, Anthony P. McFadden, Mihir Pendharkar +3
In an ideal InAs/GaSb bilayer of appropriate dimension in-plane electron and hole bands overlap and hybridize, and a topologically non-trivial, or quantum spin Hall (QSH) insulator…
Engineering the breaking of time-reversal symmetry in gate-tunable hybrid ferromagnet/topological insulator heterostructures
Joon Sue Lee, Anthony Richardella, Robert D. Fraleigh +3
Studying the influence of breaking time-reversal symmetry on topological insulator surface states is an important problem of current interest in condensed matter physics and could…
Transport studies of epi-Al/InAs 2DEG systems for required building-blocks in topological superconductor networks
Joon Sue Lee, Borzoyeh Shojaei, Mihir Pendharkar +7
One-dimensional (1D) electronic transport and induced superconductivity in semiconductor nano-structures are crucial ingredients to realize topological superconductivity. Our appro…
Epitaxy of Advanced Nanowire Quantum Devices
Sasa Gazibegovic, Diana Car, Hao Zhang +20
Semiconductor nanowires provide an ideal platform for various low-dimensional quantum devices. In particular, topological phases of matter hosting non-Abelian quasi-particles can e…
Unidirectional spin Hall magnetoresistance in topological insulator/ferromagnetic layer heterostructures
Yang Lv, James Kally, Delin Zhang +4
The large spin orbit coupling in topological insulators results in helical spin-textured Dirac surface states that are attractive for topological spintronics. These states generate…
Faraday rotation due to surface states in the topological insulator (BiSb)Te
Yinming Shao, Kirk W. Post, Jhih-Sheng Wu +9
Using magneto-infrared spectroscopy, we have explored the charge dynamics of (Bi,Sb)Te thin films on InP substrates. From the magneto-transmission data we extracted three d…
