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…
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…
Anomalous Nonlinear Magnetoconductivity in van der Waals Magnet CrSBr
Junhyeon Jo, Manuel Suárez-RodrÃguez, Samuel Mañas-Valero +6
Nonlinear magnetoconductivity (NLMC) is a nonreciprocal transport response arising in non-centrosymmetric materials. However, this ordinary NLMC signal vanishes at zero magnetic fi…
