RF Nano-Spectroscopy: The "6th sense" for STM

Modern nanoscience approaches the atomic scale: Individual atoms, rather than ensembles, carry the functionalities of man-made devices (switching, storing, calculating, catalyzing, etc). While single-atom imaging is routine since the advent of the scanning tunneling microscope (STM) in the ‘80s, their chemical identification is difficult. My group develops a “6th sense” that turns the STM from an imaging- to an identification tool with atomic resolution.

Low-temperature (LT) scanning tunneling microscopy (STM) and -spectroscopy (STS) are the methods of choice for studying electronic and geometric properties of matter at the atomic scale. We develop the low-temperature STM technique towards the detection of radio frequency (rf) signals up to several GHz. Our present focus is Single-Spin Spectroscopy with sub-nanometer spatial resolution.
