Models for plasmonic THz detectors based on graphene split-gate FETs with lateral p-n junctions

摘要

We propose and analyze the resonant plasmonic terahertz detectors based on the split-gate field-effect transistors with electrically induced p-n junctions and graphene and perforated graphene channels. The perforation of the p-n junction depletion region leads to the tunneling suppression and the substantial reinforcement of the detector resonant response.
