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…
Symmetry-breaking and spin-blockage effects on carrier dynamics in single-layer tungsten diselenide
Ro-Ya Liu, Meng-Kai Lin, Peng Chen +10
Understanding carrier creation and evolution in materials initiated by pulsed optical excitation is central to developing ultrafast optoelectronics. We demonstrate herein that the…
Comment on "Chiral Phase Transition in Charge Ordered 1T-TiSe2" and Supplementary Material on "First-order Forbidden X-ray Diffraction"
Meng-Kai Lin, Joseph A. Hlevyack, Peng Chen +2
A prior report of the emergence of chirality for the (2x2x2) charge density wave (CDW) in TiSe2 has attracted much interest; the drastic symmetry breaking is highly unusual with fe…
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…
