  • Abstract
    We found that a transistor with a graphene channel irradiated with He ion beams can have a transport gap of up to 380 meV. We made novel dual-gated transistors using such a channel and obtained an on-off ratio up to 103 at 200 K. This novel device has a channel region between dual gates, and the polarity of the transistor (n- or p-type) can be electrostatically reversed by simply flipping the bias polarity of one of the dual gates.
