Abstract:
1. A transistor, comprising: a source; a drain; a gate, said gate including a discharging element and a graphene sheet located between said source and said drain, said graphene sheet in direct contact with said discharging element, said graphene sheet having a substantially zero bandgap, said graphene sheet further receiving incident radiation which impinges on said graphene sheet; said incident radiation freeing electrons in said graphene due to said zero bandgap; an electrical field in electrical communication with said graphene sheet, to prevent said electrons from recombining with said graphene sheet; and, said graphene sheet having a width with a decreasing taper, from a maximum width distal to said discharging element to a minimum width proximate to said discharging element, to allow said electrons to move towards said discharging element.
