Graphene Flagship parnter NPL just launched a service to measure the electrical transport properties of materials and devices, including sheet resistance, resistivity, carrier type, density, and mobility.
Mar García-Hernandez of the Spanish National Research Council (CSIC) is the leader of the Graphene Flagship Work Package Enabling Materials, which is focused on development of scalable synthesis methods for graphene and other layered materials.
Researchers from the Graphene Flagship have predicted and demonstrated a giant spin anisotropy in graphene, paving the way for new spintronic logic devices. This landmark collaborative effort shows the Flagship’s role in rapid progress, from theoretical concept to experimental confirmation.

Electronics is based on the manipulation of electrons and other charge carriers, but in addition to charge, electrons possess a property known as spin. When spin is manipulated with magnetic and electric fields, the result is a spin-polarised current that carries more information than is possible with charge alone. Spin-transport electronics, or spintronics, is a subject of active investigation within Europe’s Graphene Flagship.
