Observation of a Smoothly Tunable Dirac Point in
Sean Howard, Arjun Raghavan, Davide Iaia +9
State-of-the-art topological devices require the use topological surface states to drive electronic transport. In this study, we examine a tunable topological system, $Ge(Bi_{x}Sb_…
In-situ strain tuning of the Dirac surface states in Bi2Se3 films
David Floetotto, Yang Bai, Yang-Hao Chan +12
Elastic strain has the potential for a controlled manipulation of the band gap and spin-polarized Dirac states of topological materials, which can lead to pseudo-magnetic-field eff…
Experimental and Theoretical Electronic Structure and Symmetry Effects in Ultrathin NbSe2 Films
Cai-Zhi Xu, Xiaoxiong Wang, Peng Chen +6
Layered quasi-two-dimensional transition metal dichalcogenides (TMDCs), which can be readily made in ultrathin films, offer excellent opportunities for studying how dimensionality…
Quantum-spin-Hall insulator with a large gap: single-layer 1T' WSe
P. Chen, W. -W. Pai, Y. -H. Chan +6
Two-dimensional (2D) topological insulators (TIs) are promising platforms for low-dissipation spintronic devices based on the quantum spin Hall (QSH) effect, but experimental reali…
Emergence of charge density waves and a pseudogap in single-layer TiTe2
P. Chen, Woei Wu Pai, Y. -H. Chan +8
Two-dimensional materials constitute a promising platform for developing nanoscale devices and systems. Their physical properties can be very different from those of the correspond…
Gapped Electronic Structure of Epitaxial Stanene on InSb(111)
Cai-Zhi Xu, Yang-Hao Chan, Peng Chen +7
Stanene (single-layer grey tin), with an electronic structure akin to that of graphene but exhibiting a much larger spin-orbit gap, offers a promising platform for room-temperature…
Photoemission Circular Dichroism and Spin Polarization of the Topological Surface States in Ultrathin Bi2Te3 Films
C. -Z. Xu, Y. Liu, R. Yukawa +4
Circular dichroism (CD) observed by photoemission, being sensitive to the orbital and spin angular momenta of the electronic states, is a powerful probe of the nontrivial surface s…
Elemental topological Dirac semimetal: α-Sn on InSb(111)
Cai-Zhi Xu, Yang-Hao Chan, Yige Chen +12
Three-dimensional (3D) topological Dirac semimetals (TDSs) are rare but important as a versatile platform for exploring exotic electronic properties and topological phase transitio…
