Understanding the image contrast of material boundaries in IR nanoscopy reaching 5 nm spatial resolution
Stefan Mastel, Alexander A. Govyadinov, Curdin Maissen +3
Scattering-type scanning near-field optical microscopy (s-SNOM) allows for nanoscale resolved Infrared (IR) and Terahertz (THz) imaging, and thus has manifold applications ranging…

THz nanofocusing with cantilevered THz-resonant antenna tips
S. Mastel, M. Lundeberg, P. Alonso-Gonzalez +7
We developed THz-resonant scanning probe tips, yielding strongly enhanced and nanoscale confined THz near fields at their tip apex. The tips with length in the order of the THz wav…
