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…
Restoring Pristine Bi2Se3 Surface with an Effective Se Decapping Process
Jixia Dai, Wenbo Wang, Matthew Brahlek +4
High quality thin films of topological insulators (TI) such as Bi2Se3 have been successfully synthesized by molecular beam epitaxy (MBE). Although the surface of MBE films can be p…
Hierarchical stripe phases in IrTe2 driven by competition between Ir dimerization and Te bonding
Jixia Dai, Kristjan Haule, J. J. Yang +3
Layered 5d transition metal dichalcogenide (TMD) IrTe2 is distinguished from the traditional TMDs (such as NbSe2) by the existence of multiple CDW-like stripe phases and supercondu…
Local density of states study of a spin-orbit-coupling induced Mott insulator SrIrO
Jixia Dai, Eduardo Calleja, Gang Cao +1
We present scanning tunneling microscopy and spectroscopy experiments on the novel J_eff = 1/2 Mott insulator Sr2IrO4. Local density of states (LDOS) measurements show an intrinsic…
Microscopic evidence for strong periodic lattice distortion in 2D charge-density wave systems
Jixia Dai, Eduardo Calleja, Jacob Alldredge +7
In the quasi-2D electron systems of the layered transition metal dichalcogenides (TMD) there is still a controversy about the nature of the transitions to charge-density wave (CDW)…
The k-space Origins of Scattering in Bi2Sr2CaCu2O8+x
Jacob W. Alldredge, Eduardo M. Calleja, Jixia Dai +3
We demonstrate a general, computer automated procedure that inverts the q-space scattering data measured by spectroscopic imaging scanning tunneling microscopy (SI-STM) to determin…
