TERAHERTZ AND INFRARED PHOTODETECTORS BASED ON VERTICAL GRAPHENE VAN DER WAALS HETEROSTRUCTURES: CONCEPTS, FEATURES OF OPERATION AND CHARACTERISTICS

摘要

We discuss the concept and evaluate performance of the terahertz (THz) and infrared (IR) photodetectors based on the recently proposed vertical graphene layer van der Waals heterostructures. The proposed graphene layer infrared photodetectors (GLIPs) are compared with other types of THz/IR phototodetectors.
