  • A METHOD OF PRODUCING AN ELECTRONIC DEVICE PRECURSOR
    Publication number: 20260173769
    Abstract: There is provided a method of producing an electronic device precursor, in particular a method which comprises forming ohmic contacts on the substrate, each in contact with an edge portion of a dielectric-material-capped graphene layer structure, and coating the contacts, and at least one region of the capped structure, with a further dielectric material. The present invention also provides an electronic device precursor comprising a dielectric-material-capped graphene layer structure. The electronic device precursor is preferably for a Hall effect sensor.
