Double band inversion in the topological phase transition of Ge1-xSnx alloys
Rui Tan, Qirui Yang, Ruiyuan Chen +5
We use first-principles simulation and virtual crystal approximation to reveal the unique double band inversion and topological phase transition in Ge1-xSnx alloys. Wavefunction pa…
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…
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…
Band Topology and Dichroic Signature of Bismuth
Guang Bian, Tay-Rong Chang, Xiaoxiong Wang +3
Bismuth has been the key element in the discovery and development of topological insulator materials. Previous theoretical studies indicated that Bi is topologically trivial and it…
Engineering Multiple Topological Phases in Nanoscale Van der Waals Heterostructures: Realisation of -Antimonene
Tobias Märkl, Pawel J. Kowalczyk, Maxime Le Ster +7
Van der Waals heterostructures have recently been identified as providing many opportunities to create new two-dimensional materials, and in particular to produce materials with to…
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…
