3.4. Potential applications to light emission & photodetection• Graphene nanoribbons: semiconducting energy gaps may be engineeredby the controlling the width, from 0 ~ 200 meV.• Graphane: semiconducting energy gaps may be engineered by controllingthe hydrogen coverage, from 0 ~ 3.5 eV.Device conceptLight emissionThe light emittingprocess may bereversed <strong>for</strong> thedetection ofphotocurrents.t(or graphenenanoribbons)• Future work: measurements of the I-V characteristics & photocurrents.
