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 ...
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 ...
The objective of this work is to fabricate a scanning probe sensor that combines the well-established method for atomic force microscopy, employing a micro-machined Si cantilever and integrated tip, with a probe for the optical near field. A photosensitive ...
Fluorescence resonance energy transfer (FRET) was obsd. between donor dye mols. deposited onto the sample surface and acceptor dye mols. deposited onto the scanning near-field optical microscope (SNOM) or at. force microscope tip. FRET was obsd. only when ...
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 ...
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 ...
Lateral force microscopy in the wearless regime was used to study the friction behavior of a lipid monolayer on mica. In the monolayer, condensed domains with long-range orientational order of the lipid molecules were present. The domains revealed unexpect ...

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 ...
We performed lateral force microscopy on thiolipid Langmuir-Blodgett (LB) films physisorbed on mica substrates with a silicon tip of an at. force microscope. The structure of condensed domains, reflecting their sym. morphol., was obsd. The lateral (frictio ...
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 ...
