Topological phase transition with nanoscale inhomogeneity in (BiIn)Se
Wenhan Zhang, M. X. Chen, Jixia Dai +4
Topological insulators are a class of band insulators with non-trivial topology, a result of band inversion due to the strong spin-orbit coupling. The transition between topologica…
Toward the intrinsic limit of topological insulator Bi2Se3
Jixia Dai, Damien West, Xueyun Wang +5
Combining high resolution scanning tunneling microscopy and first principle calculations, we identified the major native defects, in particular the Se vacancies and Se interstitial…
Time reversal symmetry breaking superconductivity in topological materials
Yunsheng Qiu, Kyle Nocona Sanders, Jixia Dai +5
Fascinating phenomena have been known to arise from the Dirac theory of relativistic quantum mechanics, which describes high energy particles having linear dispersion relations. El…
Record Surface State Mobility and Quantum Hall Effect in Topological Insulator Thin Films via Interface Engineering
Nikesh Koirala, Matthew Brahlek, Maryam Salehi +11
Material defects remain as the main bottleneck to the progress of topological insulators (TIs). In particular, efforts to achieve thin TI samples with dominant surface transport ha…
