Sum-frequency generation (SFG) is a powerful vibrational spectroscopy that can selectively probe molecular structures at surfaces and interfaces, but its spatial resolution has been limited to the ...

Researchers led by Prof. ZHOU Wu from the University of Chinese Academy of Sciences (UCAS) and Prof. Sokrates T. Pantelides of Vanderbilt University have pushed the sensitivity of single-atom ...

Lithuanian researchers at the Center for Physical Sciences and Technology (FTMC), Habil. Dr. Gediminas Niaura and Dr. Martynas Talaikis, together with international colleagues, have for the first time ...

This property enables SFG spectroscopy to serve as a powerful molecular vibrational spectroscopic tool in the infrared wavelength region. A more notable feature of SFG spectroscopy is its surface ...
