Acquisition of Closed-Cycle Optical Cryostat to Investigate 1D and 2D Material Plasmonic Structures

Abstract

Two-dimensional (2D) materials, such as metallic graphene, insulating hexagonal boron nitride,and semiconducting transition metal dichalcogenides, form a material platform for investigatingelectronic, optical and plasmonic effects at the atomically thin limit. In this proposal, we request aclosed-cycle optical cryostat capable of achieving sample temperatures of 3 K – 300 K. The cryostat will be used to investigate how surface plasmon polaritons in conductive waveguidenanostructures can be controlled using both delocalized excitons and single quantum emitters inmonolayer semiconductors. We will design and fabricate novel plasmonic structures and usecoherent nonlinear optical spectroscopy techniques to investigate coupling between surfaceplasmon polaritons that are mediated by the nonlinear response of the 2D semiconductor. Theproposed instrumentation includes a nano-positioning system that will enable low temperaturesample positioning. The instrumentation will allow for the optical and electronic investigation ofthe novel plasmonic devices for applications to high speed and quantum information processing.These emerging technologies have broad applications that are relevant to DoD interests includingscientific computing, encryption and cybersecurity.
