Ultrafast terahertz scanning tunneling microscopy of atomically precise nanostructures

Terahertz scanning tunneling microscopy (THz-STM) is a new ultrafast imaging technique that provides access to femtosecond dynamics on the atomic scale for the first time. Its versatility enables numerous scientific opportunities, including ultrafast studies of electron dynamics within single molecules and nanostructures. In this talk, I will introduce a conceptual basis for ultrafast terahertz scanning tunneling spectroscopy, show THz-STM snapshot imaging of local electron densities, and discuss future directions in the field.
