Review of Nanolayered Post-transition Metal Monochalcogenides: Synthesis, Properties, and Applications
Mingyu Yu, Maria Hilse, Qihua Zhang +3
Nanolayered post-transition metal monochalcogenides (PTMMCs) stand out as promising advanced two-dimensional (2D) materials. Beyond inheriting the general advantages associated wit…
Topological insulator-based Dirac hyperbolic metamaterial with large mode indices
Zhengtianye Wang, Saadia Nasir, Yongchen Liu +3
Hyperbolic metamaterials (HMMs) are engineered materials with a hyperbolic isofrequency surface, enabling a range of novel phenomena and applications including negative refraction,…
Surface plasmon-phonon-magnon polariton in a topological insulator-antiferromagnetic bilayer structure
D. Quang To, Zhengtianye Wang, Yongchen Liu +6
We present a robust technique for computationally studying surface polariton modes in hybrid materials. We use a semi-classical model that allows us to understand the physics behin…
Bi2Se3 Growth on (001) GaAs Substrates for Terahertz Integrated Systems
Yongchen Liu, Wilder Acuna, Huairuo Zhang +8
Terahertz (THz) technologies have been of interest for many years due to the variety of applications including gas sensing, nonionizing imaging of biological systems, security and…
Strong coupling between a topological insulator and a III-V heterostructure at terahertz frequency
D. Quang To, Zhengtianye Wang, Q. Dai Ho +8
We probe theoretically the emergence of strong coupling in a system consisting of a topological insulator (TI) and a III-V heterostructure using a numerical approach based on the s…
In-Plane Plasmon Coupling in Topological Insulator BiSe Thin Films
Saadia Nasir, Zhengtianye Wang, Sivakumar V. Mambakkam +1
The surface states of the 3D topological insulator (TI), BiSe, are known to host two-dimensional Dirac plasmon polaritons (DPPs) in the terahertz spectral range. In TI thin…
Strong coupling in semiconductor hyperbolic metamaterials
Patrick Sohr, Dongxia Wei, Zhengtianye Wang +1
Semiconductor-based layered hyperbolic metamaterials (HMMs) house high-wavevector volume plasmon polariton (VPP) modes in the infrared spectral range. VPP modes have successfully b…
Real-space nanoimaging of THz polaritons in the topological insulator Bi2Se3
Shu Chen, Andrei Bylinkin, Zhengtianye Wang +6
Plasmon polaritons in topological insulators attract attention from a fundamental perspective and for potential THz photonic applications. Although polaritons have been observed by…
Optimization of the growth of the van der Waals materials Bi2Se3 and (Bi0.5In0.5)2Se3 by molecular beam epitaxy
Zhengtianye Wang, Stephanie Law
The naturally existing chalcogenide Bi2Se3 is topologically nontrivial due to the band inversion caused by strong spin-orbit coupling inside the bulk of the material. The surface s…
