BERKELEY, CA — Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have performed the first scanning ...

A new technique that combines the chemical sensitivity of optical vibronic spectroscopy with the atomic resolution of scanning tunnelling microscopy (STM) has been developed by Guillaume Schull and ...

The RHK R9 STM is capable of atomic resolution imaging and tunneling spectroscopy measurements on conductive and semiconductor surfaces under ultra-high vacuum, both at room temperature (~295K) and at ...

Scanning Tunneling Microscopes (STMs) are amazing tools which can manipulate singular atoms, but they cannot characterize these atoms as they act only on the outer electron shell. Meanwhile X-ray ...

Vibrational sum-frequency generation (VSFG) is a nonlinear spectroscopic method widely used to investigate the molecular structure and dynamics of surface systems. However, in far-field observations, ...

Nonlinear optics describes the regime in which the response of a material to an applied electromagnetic field depends nonlinearly on the field amplitude. Whereas in linear optics the induced ...
