Anti-reflection coatings for highly anisotropic materials in the mid infrared
Hongyan Mei, Jin-Woo Cho, Jae-Seon Yu +6
We develop and optimize thin anti-reflection coatings (ARCs) for highly anisotropic materials in the mid infrared. Unlike conventional ARCs that assume nearly isotropic refractive…
Emergent Atomic Scale Polarisation Vortices in BaTiS3
Boyang Zhao, Gwan Yeong Jung, Shantanu Singh +21
Topological defects, such as vortices and skyrmions in magnetic and dipolar systems, can give rise to properties that are not observed in typical magnets and dielectrics. Here, we…
Phase-change materials for volatile threshold resistive switching and neuronal device applications
Huandong Chen, Jayakanth Ravichandran
Volatile threshold resistive switching and neuronal oscillations in phase-change materials, specifically those undergoing metal-to-insulator transitions, offer unique attributes su…
Towards Atomic-Scale Control over Structural Modulations in Quasi-1D Chalcogenides for Colossal Optical Anisotropy
Guodong Ren, Shantanu Singh, Gwan Yeong Jung +10
Optically anisotropic materials are sought after for tailoring the polarization of light. Recently, colossal optical anisotropy was reported in a quasi-one-dimensional chalcogenide…
Strain-driven stabilization of a room-temperature chiral multiferroic with coupled ferroaxial and ferroelectric order
Guodong Ren, Gwan Yeong Jung, Huandong Chen +9
Noncollinear ferroic materials are sought after as testbeds to explore the intimate connections between topology and symmetry, which result in electronic, optical and magnetic func…
Electrical contacts for high performance optoelectronic devices of BaZrS3 single crystals
Huandong Chen, Shantanu Singh, Mythili Surendran +3
Chalcogenide perovskites such as BaZrS3 are promising candidates for next generation optoelectronics such as photodetectors and solar cells. Compared to widely studied polycrystall…
