Schematic of the experimental s-SNOM apparatus

Caption

A tunable FEL generates narrowband terahertz radiation, which is focused onto the s-SNOM tip and is backscattered into a photoconducting detector. Inset: terahertz light scatters off the edge of a HfDC flake, launching PhPs, which are then coupled out to free space by the s-SNOM tip. The layered crystal structure of vdW-bonded HfSe2 is also shown.
