  • Direct Mapping of the solid–liquid adhesion energy with subnanometre resolution
    Nature Nanotechnology, 2010
    Co-Authors: Kislon Voïtchovsky, Jeffrey J. Kuna, Sonia Antoranz Contera, Erio Tosatti, Francesco Stellacci
    Abstract:

    A commercial atomic force microscope can be used to obtain atomic- or molecular-level-resolution images and interfacial energy maps of hard and soft materials in liquids. Solid–liquid interfaces play a fundamental role in surface electrochemistry^ 1 , catalysis^ 2 , wetting^ 3 , self-assembly^ 4 and biomolecular functions^ 5 . The interfacial energy determines many of the properties of such interfaces, including the arrangement of the liquid molecules at the surface of the solid. Diffraction techniques are often used to investigate the structure of solid–liquid interfaces^ 6 , but measurements of irregular or inhomogeneous interfaces remain challenging. Here, we report atomic- and molecular-resolution images of various organic and inorganic samples in liquids, obtained with a commercial atomic force microscope operated dynamically with small-amplitude modulation. This approach uses the structured liquid layers close to the solid to enhance lateral resolution. We propose a model to explain the mechanism dominating the image formation, and show that the energy dissipated during this process is related to the interfacial energy through a readily achievable calibration curve. Our topographic images and interfacial energy maps could provide insights into important interfaces.

  • Spin wave hybridization via Direct Mapping of spin wave evolution in ferromagnetic microstructures
    Journal of Applied Physics, 2011
    Co-Authors: Lihui Bai, Y. S. Gui, Z. H. Chen, S. C. Shen, Junsaku Nitta, L. E. Hayward, M. P. Wismayer, B. W. Southern
    Abstract:

    Confined spin waves in single magnetic microstrips are investigated using a microwave photovoltage technique. Direct Mapping of the spin wave evolution between surface, edge, and central modes is achieved by tuning the Direction of the applied magnetic field. Both theoretical and numerical methods are used to study the evolution of the excitations and provide excellent agreement with the experimental results. The most prominent feature observed is a mode repulsing behavior which indicates mode hybridization in the dipole dominated part of the spin wave spectrum.
