Rate Programmable Ionic-Redox Switching with Tunable Volatility in CuCrP2S6
Suzanne Lancaster, Francesco Calavalle, Mayank Sharma +8
Metal thiophosphates are emerging as a multifunctional material platform for neuromorphic electronics due to their accessible polar phases and ion dynamics on biologically relevant…
Second-Order Synaptic Memory using Inherent Plasticity of Moiré Superlattices
Tanweer Ahmed, Kenji Watanabe, Takashi Taniguchi +2
Achieving synaptic functionality electronically in a single-element quantum material is a fundamental challenge, as conventional methods rely on the introduction of extrinsic charg…
Ferroelectric hysteresis in singly aligned graphene-hBN moiré superlattices
Bao Q. Tu, Tanweer Ahmed, Garen Avedissian +7
Ferroelectric materials have the unique ability to maintain an electric polarization which can be reversed under an external applied electric field. This property makes them valuab…
Surface lone-pair polarization probed by quantum-geometric transport in tellurium
Nathanael N. Batista, Wendel S. Paz, Manuel Suárez-RodrÃguez +10
Stereochemically active lone pairs are ubiquitous microscopic sources of polarity in molecules and solids, but their collective behavior in crystals is often hidden by symmetry or…
Signatures of time-reversal-symmetry breaking in multiband 2H-TaS2 revealed by zero-field Josephson nonreciprocity
Daniel Margineda, David Caldevilla-Asenjo, Yuriy Yerin +7
Superconductors that spontaneously break time-reversal symmetry host complex order parameters and are widely regarded as a hallmark of unconventional superconductivity. Whether suc…
A new helical InSeI polymorph: crystal structure and polarized Raman spectroscopy study
LucÃa Olano-Vegas, Davide Spirito, Evgeny Modin +7
Tetragonal InSeI is an interesting low-dimensional metal chalcohalide due to its composition and anisotropic crystal structure composed of helical chains, which give rise to optoel…
