Spectral response of plasmon resonant nanoparticles with a non-regular shape
We study the plasmon resonances of 10 - 100 (nm) two-dimensional metal particles with a non-regular shape. Movies illustrate the spectral response of such particles in the optical range. Contrary to particles with a simple shape (cylinder, ellipse) non-reg ...
Optical Society of America2000In situ imaging of threading dislocation terminations at the surface of GaN(0001) epitaxially grown on Si(111)
Scanning tunneling microscopy (STM) is used in situ to study threading dislocation terminations at the surface of GaN grown by molecular beam epitaxy on a Si(111) surface. The associated surface depressions are imaged at the nanometer scale, giving a new i ...
2000Force-distance curves by atomic force microscopy
Atomic force microscopy (AFM) force-distance curves have become a fundamental tool in several fields of research, such as surface science, materials engineering, biochemistry and biology. Furthermore, they have great importance for the study of surface int ...
Elsevier1999Surface Second Harmonic generation in the Characterization of Anodic Sulphide and Oxide Films on Hg1-xCdxTe (MCT)
Rotation anisotropy by second harmonic generation (SHG) is carried out on epitaxial Hg1−xCdxTe (MCT) and oxide- and sulphide-covered MCT surfaces and shows the fourfold symmetry pattern expected from the {100} surface (C4v symmetry). The uneven nature of t ...
1999Evaporation from nonvegetated surfaces: Surface aridity methods and passive microwave remote sensing
The use of remotely sensed near-surface soil moisture for the estimation of evaporation is investigated. Two widely used parameterizations of evaporation, the so-called alpha and beta methods, which use near-surface soil moisture to reduce some measure of ...
1999Simultaneous determination of chemical diffusion and surface exchange coefficients of oxygen by the potential step technique
Jan Van Herle, Stefan Diethelm, Alexandre Closset
Oxygen diffusion is treated in a dense electronically conducting cobaltate pellet blocked ionically on one surface, electronically on the other, and sealed on its cylindrical periphery. A procedure is developed for extracting the chemical diffusion and sur ...
1999Pulsed laser deposition for in-situ photoemission studies on YBa2Cu3O7-delta and related oxide films
Giorgio Margaritondo, Marco Grioni, Davor Pavuna
We describe a new pulsed laser deposition (PLD) system that is linked to an angle-resolved photoemission (ARPES) chamber at the Synchrotron Radiation Center (SRC) in Wisconsin, USA. We also discuss our first results on epitaxially grown YBa2Cu3O7-delta (YB ...
