Bio-Nanotechnology Infrastructure and Technology Oriented Research
Abstract
FIU research concentrated in the following areas of development: nanoelectronics, bio-nanosensors, and nanomaterials, processes, and characterization. Five projects were supported: next generation information storage devices-both three-dimensional magnetic and protein-based, high power cold cathodes for microwave generators, carbon nanotube-based bio-sensors, silicon/polymer nanophotonics, and doped nanodiamonds and nanoceramic lasers for future devices. In magnetic storage devices, this work has resulted in patterned soft underlayer metallizations to localize the recording and sensitivity fields in 3-D recording media and the development of a prototype using focused ion beam nanomachining to manufacture a 3-D magnetic system including a 3-D patterned media and magnetic transducer. In microwave generators, demonstrated thin-multiwall carbon nanotubes (tMWNTs) with low turn-on field (approx. 0.5 V/micron) and stable operation and synthesized multistage tungsten oxide field emitters with high emission current ( approx. 180 microA/1tip). Demonstrated two electron multiplier concepts using both alumina continuous multiplier and a low temperature cofired ceramic (LTCC)/Ag dynode structure. Demonstrated both an ultra-small Si ring resonators characterized by a 2 micron radius on a single ring , with a free-spectral range of 50 nm or 6THz and an operating wavelength of 1510-1610nm and a silicon Horizontal Slot waveguide coupler with approximately 80% fiber-chip efficiency.
