A simple method has been developed for the prodn. of Au surfaces which are uniformly flat over large areas. Si wafers serve as substrates for the evapn. of thin Au layers. A glass slide glued onto the Au film allows successful sepn. of the Au layer from th ...
Three-dimensional coherent islands formed during the highly strained growth of In(0.3)G(0.7)As on GaAs(001) are studied by scanning tunneling microscopy. High-resolution images evidence two different types of surface reconstructions between the top and the ...
A dual axis, raster-scanning laser display based on a monolithic micromachined scanning mirror is presented. The scanner consists of a micromirror located at the end of a thermally actuated bimorph beam. The novelty of the device is that an "L"-shape canti ...
High-density arrays (5 x 10(6) cm(-1)) of parallel nanowires have been grown using the vicinal Pt(997) surface as a template. Single monatomic rows of Ag and Cu can be deposited with subrow precision. We demonstrate real-time monitoring and characterizatio ...
Surfactant-mediated epitaxy (SME) of III-V semiconductors is studied in the case of the GaAs(001) growth using Te as surfactant. To account for the strong surface segregation of Te, a phenomenological exchange mechanism is used. This process explains the r ...
The ordering of two-dimensional Ag islands embedded in the Pt(111) surface layer has been investigated using He-atom scattering and scanning tunneling microscopy. At lower Ag coverage the embedded islands consist of compact clusters (disks) arranged into a ...
Monolayers of thiols self-assembled on Au (111) can be made hydrophilic by functionalizing the surface with polar endgroups. The authors present scanning tunneling microscopy (STM) images of 2 such hydrophilic monolayers, one terminated by hydroxyl (mercap ...
We show that strong optical field gradients can be created at the tip apex of a local probe microscope illuminated by an external light source. We demonstrate that these confined fields can be easily, precisely and continuously tuned by changing the polari ...
We report on the first successful operation of a scanning force microscope using microfabricated capacitive force sensors. The sensors, which are made from single crystal silicon on insulator wafers, consist of a cantilever spring with integrated tip at th ...
We present the results of mol. dynamics calcns. carried out on self-assembled monolayers (SAMs) formed from alkyl thiols chemisorbed on a gold (111) substrate. The alkyl tails are functionalized by polar groups (-NH2) with the potential of forming hydrogen ...
