Nanoscience and technology

Definition

Nanoscience and technology is the branch of science that studies systems and manipulates matter on atomic, molecular and supramolecular scales (the nanometre scale). On such a length scale, quantum mechanical and surface boundary effects become relevant, conferring properties on materials that are not observable on larger, macroscopic length scales.

    Spintronic devices with full electrical control rely on electrical generation and detection of spin currents in the absence of magnetic materials. Here, the authors use Pt, a non-magnetic metal, to generate and detect pure spin currents in a few-layer graphene channel, achieving a remarkable spin-to-charge voltage signal at room temperature.

    The development of future computation devices will be aided by a better understanding of the physics underlying material behaviors. Using thermoreflectance and spatially resolved X-ray microscopy, Kumar et al. elucidate the origin of two types of negative differential resistance in NbO2 memristors.
