Terahertz scanning tunneling microscopy on metals, semiconductors, and carbon nanostructures
DownloadSpring 2024
Marin Calzada, Jesus Alejandro
Scanning probe microscopes routinely provide atomic resolution of numerous materials, but lack the tools to investigate their ultrafast dynamics. Laser pulses can be generated in the femtosecond or even attosecond regime, but their spatial application is restricted by the diffraction limit....

Ultrafast terahertz (THz) spectroscopy is presently the most powerful tool available to materials scientists for directly probing ultrafast conductivity dynamics. Its low center frequency and phase-resolved measurement, which yields sub-picosecond temporal resolution, make it ideally suited for...
