Nanodevices, Nanophotonics, and Nanosystems
Electronics powered by microrelays smaller than a dime, tiny optoelectronic devices performing complex logic functions, space ships equipped with lightweight tools with the strength of steel-all this and more will be available in the near future, thanks to nanotechnology breakthroughs engineered by Georgia Tech scientists like Dr. Mark Allen and Dr. Z.L. Wang, internationally recognized experts in the field of nanoscience and nanotechnology.
Electrical and Computer Engineering Professor Mark Allen is on the case of making better electronics. A participant in the Microsystems Research Center and the Packaging Research Center, Allen is studying magnetically-actuated microrelays smaller than a dime that have potential use in automobile electronics, test equipment, and other areas where low-actuation voltages are required.
But nanotechnology has the ability to affect all areas of life, not just electronics, according to Georgia Tech Materials Science and Engineering Professor Z.L. Wang, an expert in nanotechnology who was recently named by Science Watch as one of the world's most cited authors in nanotechnology research. The director of Georgia Tech's Center for Nanoscience and Nanotechnology, Wang studies a variety of nano-sized materials and shapes that will be used to create tiny devices, robots, and sensors. He has created nanobelts, which serve as the basis for very small sensors, flat-panel display components, and electronic and optoelectronic nanodevices, and more recently, nanorings, which can be used for nanometer-scale sensors, resonators and transducers.
Nanotechnology's far-reaching capabilities to transform materials into commercially viable products make for cool research across Georgia Tech's campus. Physics Assistant Professor Mike Chapman pursues quantum studies using lasers to confine and cool atoms to micro-Kelvin temperatures inside a vacuum chamber, while Dr. C.P. Wong, a Regents' professor of Materials Science and Engineering, researches polymeric materials (organic and inorganic) for use in low-cost, high-performance nano-functional materials and manufacturing processes.
Chemistry Professors Seth Marder and Joseph Perry are developing a device the size of a laser printer to manufacture nano-sized materials using a laser-based process that allows them to essentially carve structures from the inside out.
School of Chemistry and Biochemistry Associate Professor Robert Dickson has developed nanometer-scale optoelectronic devices that perform complex logic operations that could provide the foundation for the development of molecular-scale computing.
And Chemistry Professor Lawrence Bottomley has joined with NASA to find the most lightweight polymers to combine with carbon nanotubes to produce strong,lightweight composite materials for use on space vehicles.
From electronics to lasers, from organic materials to space-age composites, Georgia Tech researchers prove that Tech is on the cutting edge of nanotechnology, producing products that bring tomorrow into focus today.
