Classifier circuits with graphene transistors
A classifier circuit includes an array of dual gate graphene transistors, each of the transistors having a source, a top gate receiving one of an input voltage to be evaluated or a reference voltage, a bottom or embedded gate receiving the other of the input voltage or reference voltage and a drain, the source and drain contacting a graphene channel One of the source and the drain is connected to a voltage source. A common output combines output current of a plurality of the dual gate graphene transistors, which current varies in response to the difference between the input voltage and the reference voltage. A method for forming a classifier transistor with high remanent polarization forms dielectric with ferroelectric capability on a low resistivity substrate. A non-ferroelectric oxide layer is formed on the dielectric. A window is opened, and a graphene channel is formed in the window.
