We explore the role of molecular vibrations in chirality-induced spin selectivity (CISS) effect context charge transport through a nanojunction. employ mixed quantum-classical approach that combines Ehrenfest dynamics for with hierarchical equations motion method electronic degrees freedom. This treats nonequilibrium manner, which is crucial nanojunctions. To vibrational on selectivity, we also introduce new figure merit, displacement polarization, quantifies difference displacements opposing lead magnetizations. analyze single trajectories, investigating how depends voltage and electronic-vibrational coupling. Furthermore, investigate temperature dependence ensemble-averaged observables. demonstrate correlated time indicating driving force CISS this model within approach.

The past few decades have witnessed significant development in intercalation chemistry research aimed at precisely controlling material properties. Intercalation, as a powerful surface and interface synthesis strategy, facilitates the insertion of external guests into van der Waals (vdW) gaps two-dimensional (2D) layered materials, inducing various modulation effects (the weakening interlayer interactions, changes electronic structures, interfacial charge transfer, symmetry manipulation) to tailor properties while preserving intralayer covalent bonds. Importantly, benefiting from very diverse structures organic molecules, their enables integration molecules with wide array 2D resulting creation numerous organic–inorganic hybrid superlattices exotic properties, which brings extensive potential applications fields such spintronics, superconductor electronics, optoelectronics, thermoelectrics.

This work introduces a magnetic conductive atomic force microscopy (mc-AFM) measurement platform for determining spin polarizations, arising from the chiral-induced selectivity (CISS) effect along different directions in helical conducting fibers. By using principle that preference electron transport chiral material changes with momentum of electron, this method quantifies polarization materials, which straddle ferromagnetic electrode, i.e., by taking measurements regions to right and left electrode while it is magnetized in-plane. The working mechanism shown polyaniline (PANI) fibers, they reveal longitudinal, fiber's axis, transverse, perpendicular fiber magnetoresistance differ about factor 2. observations imply PANI fibers not consistent models attribute (or magnetoresistance) solely spinterface or spin-dependent charge injection barriers. In aggregate, new offers simplified approach extending mc-AFM resolving spin-filtered currents oriented samples.
