Topological Phase Transitions in a Hybridized Three-Dimensional Topological Insulator
Su Kong Chong, Lizhe Liu, Taylor D. Sparks +2
As the thickness of a three-dimensional (3D) topological insulator (TI) becomes comparable to the penetration depth of the surface states, quantum tunneling between surfaces turns…
Landau Levels of Topologically-Protected Surface States Probed by Dual-Gated Quantum Capacitance
Su Kong Chong, Ryuichi Tsuchikawa, Jared Harmer +2
Spectroscopy of discrete Landau levels (LLs) in bulk-insulating three-dimensional topological insulators (3D TIs) in perpendicular magnetic field characterizes the Dirac nature of…
Tunable Coupling between Surface States of a Three-Dimensional Topological Insulator in the Quantum Hall Regime
Su Kong Chong, Kyu Bum Han, Taylor D. Sparks +1
The paired top and bottom Dirac surface states, each associated with a half-integer quantum Hall (QH) effect, and a resultant integer QH conductance (νe2/h), are hallmarks of a thr…
Topological Insulator-Based van der Waals Heterostructures for Effective Control of Massless and Massive Dirac Fermions
Su Kong Chong, Kyu Bum Han, Akira Nagaoka +8
Three dimensional (3D) topological insulators (TIs) are an important class of materials with applications in electronics, spintronics and quantum computing. With the recent develop…
Enhancement in surface mobility and quantum transport of Bi_(2-x)Sb_(x)Te_(3-y)Se_(y) topological insulator by controlling the crystal growth conditions
Kyu-Bum Han, Su Kong Chong, Akira Nagaoka +4
Despite numerous studies on three-dimensional topological insulators (3D TIs), the controlled growth of high quality (bulk-insulating and high mobility) TIs remains a challenging s…
