Self-assembled Si1−xGex islands were studied in detail using atomic force microscopy. The self-assembled Si1−xGex islands were formed by a novel two-step process. First, highly strained Si1−xGex thin films (with x∼0.4) were selectively grown on a silicon wafer by chemical vapor deposition at 650 °C. The growth was followed by an annealing step perf...
The "living" radical polymerization with an iniferter was used to create micropatterned biomedical surfaces. Novel, photosensitive biomedical polymers were created by the incorporation of dithiocarbamate groups from iniferters. A second monomer layer was then irradiated onto the photosensitive polymer substrate created with the iniferter to form a ...
A process to form a silicon on insulator (SOI) structure suspended in air was demonstrated. The structure provided electrical isolation while providing good thermal contact to the substrate. Selective epitaxial growth (SEG) of silicon was to provide robust, reliable mechanical and electrical contacts between the SOI layer and the substrate. The pro...
This paper describes the fabrication and characterization of a microelectronic device for the electrical interrogation and impedance spectroscopy of biological species. Key features of the device include an all top-side processing for the formation of fluidic channels, planar fluidic interface ports, integrated metal electrodes for impedance measur...
