We demonstrate the first “nonlocal” nanoscale NIR-pump THz-probe measurements of semi-insulating GaAs using a scattering-type scanning…
We develop a super-resolution terahertz imaging technique to improve the THz image resolution beyond the diffraction…
The local dynamics on materials generate thermal evanescent waves that are strongly localized on material surfaces.…
Ultrafast IR nanoscopy – probing molecular quantum dynamics in space and time
