Surface Physics.
In the surface physics laboratory we study well-deened surfaces of solid materials as well as adsorbed atomic and molecular monolayers and ultrathin lms, prepared under ultrahigh-vacuum (UHV) conditions. In order to obtain detailed information on the geometric arrangement of the atoms within the rst few monolayers of the surface we apply predominantly electron-based techniques such as X-ray pho...
متن کاملPhysics of Surface Plasmon Resonance
In the last two decades, surface plasmon resonance (SPR) has evolved from a fairly esoteric physical phenomenon to an optical tool that is widely used in physical, chemical and biological investigations where the characterization of an interface is of interest. Recently, the field of SPR nano-optics has been added where metallic structures on a nanoscale can be designed such that they can perfo...
متن کاملAcoustic physics of surface-attached biochemical species.
In this Commentary, we discuss the paper Quantitative Determination of Size and Shape of Surface-Bound DNA Using an Acoustic Wave Sensor [Tsortos et al., Biophys. J. 94(7), 2706-2715 (2008)]. The paper under discussion presents a novel theory that uses the response of a Shear-Horizontal Surface Acoustic Wave device to characterize surface-attached double- and triple-strand DNA. The authors rela...
متن کاملThe surface physics of ice in thunderstorms
Laboratory and field studies have shown that thunderstorm electrification is principally due to rebounding collisions between ice particles and hail. Recent studies have provided clues for an understanding of the microphysics of the charging mechanism, involving the dynamics of vapor growth, molecular diffusion, and collisionally modified surface melting. The theory is in quantitative agreement...
متن کاملElastic effects of liquids on surface physics
The contact between a liquid and an elastic solid generates a stress vector depending on the curvature tensor in each point of the separating surface. For nanometer values of the mean curvature and for suitable materials, the stress vector takes significant amplitude on the surface. Although the surface average action of the liquid on the solid is the hydrostatic pressure, the local strain gene...
