Visualizing the Hidden Architecture of Molecular Films with Phase-Resolved Rotational SFG Microscopy
Ben John, Tuhin Khan, Nasim Mirzajani +3
The highly variable physico-chemical properties of thin molecular films play an essential role in numerous research fields ranging from biophysics to the fabrication of functional…
Beyond the Electric Dipole Approximation: Electric and Magnetic Multipole Contributions Reveal Biaxial Water Structure from SFG Spectra at the Air-Water Interface
Louis Lehmann, Maximilian R. Becker, Lucas Tepper +4
The interpretation of sum-frequency-generation (SFG) spectra has been severely limited by the absence of quantitative theoretical predictions of higher-order multipole contribution…
Terahertz switching of antiferromagnetic order by Néel spin-orbit torques
Yannic Behovits, Alexander L. Chekhov, Amon Ruge +13
Ultrafast electric manipulation of magnetic order in solids is critical for the development of future terahertz data processing. A fascinating concept for such high-speed operation…
Anisotropic Water Structure at Charged Interfaces Studied by Depth Resolved Vibrational SFG/DFG Spectroscopy
Ãlvaro Diaz-Duque, Vasileios Balos, Martin Wolf +2
The molecular water structure at charged aqueous interfaces is shaped by interfacial electric fields, which can induce significant anisotropy in the molecular orientations extendin…
The Importance of Layer-Dependent Molecular Twisting for the Structural Anisotropy of Interfacial Water
Alexander P. Fellows, Louis Lehmann, Ãlvaro DÃaz Duque +3
The unique structural properties of interfacial water are at the heart of a vast range of important processes in electrochemistry, climate science, and biophysics. At interfaces, w…
Full Crystallographic Imaging of Hexagonal Boron Nitride Monolayers with Phonon-Enhanced Sum-Frequency Microscopy
Niclas S. Mueller, Alexander P. Fellows, Ben John +13
Hexagonal boron nitride (hBN) is an important 2D material for van der Waals heterostructures, single photon emitters, and infrared nanophotonics. The optical characterization of mo…
