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…
Interface quality in GaSb/AlSb short period superlattices
Md Nazmul Alam, Joseph R. Matson, Patrick Sohr +2
Heterostructures including the members of the 6.1Å semiconductor family (AlSb, GaSb, and InAs) are used in infrared optoelectronic devices as well as a variety of other application…
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…
Growth of Topological Insulator Bi2Se3 Particles on GaAs via Droplet Epitaxy
Sivakumar Vishnuvardhan Mambakkam, Saadia Nasir, Wilder Acuna +2
The discovery of topological insulators (TIs) and their unique electronic properties has motivated research into a variety of applications, including quantum computing. It has been…
