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…
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
Álvaro 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, Álvaro Díaz 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…
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…
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…
THz-Driven Coherent Phonon Fingerprints of Hidden Symmetry Breaking in 2D Layered Hybrid Perovskites
Joanna M. Urban, Michael S. Spencer, Maximilian Frenzel +10
Metal-halide perovskites (MHPs) emerged as a family of novel semiconductors with outstanding optoelectronic properties for applications in photovoltaics and light emission. Recentl…
How Thick is the Air-Water Interface? -- A Direct Experimental Measurement of the Decay Length of the Interfacial Structural Anisotropy
Alexander P. Fellows, Álvaro Díaz Duque, Vasileios Balos +4
The air-water interface is a highly prevalent phase boundary with a far-reaching impact on natural and industrial processes. Water molecules behave differently at the interface com…
Spiralling molecular structures and chiral selectivity in model membranes
Alexander P. Fellows, Ben John, Martin Wolf +1
Since the lipid raft model was developed at the end of the last century, it became clear that the specific molecular arrangements of phospholipid assemblies within a membrane have…
