Anion Ordering and Phase Stability Govern Optical Band Gaps in BaZr(S,Se)3
Erik Fransson, Michael Xu, Prakriti Kayastha +6
Chalcogenide perovskites have emerged as promising lead free materials for photovoltaic and thermoelectric applications. Among them, BaZrS3 has attracted particular attention due t…
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…
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…
