Abstract

Polaritons in two-dimensional layered crystals offer an effective solution to confine, enhance and manipulate terahertz (THz) frequency electromagnetic waves at the nanoscale. In this talk I’ll review recent results in the detection of dirac plasmon polaritons at THz frequencies, in hBN-encapsulated black-phosphorus field effect transistors through THz near-field photocurrent nanoscopy and in large area topological insulators through detectorless near-field digital holography.
