Has conducted research on the microstructure of ceramics, including the fabrication of superconducting tubes and studies of the oxidation and corrosion of metals. Also has studied the microstructure of meteorites.
Developed method to bring ions in for a "soft-landing" on surfaces, providing a new way to trap and study ions and modify the outermost layer of materials. Has received national and international recognition for his work in mass spectrometry. Has served on two National Science Foundation advisory panels and a National Institutes of Health grants panel.
Has conducted pioneering research in impact damage and wave propagation in composite materials and failure and fatigue in these materials when used in aircraft and aerospace structures. Is investigating use of composites to extend life of aging aircraft. Is a fellow of American Institute of Aeronautics and Astronautics and of American Association of Mechanical Engineers.
Is a specialist in concrete and cement materials for use in construction, soil chemistry and physics, and materials surfaces. Has extensive publishing and media experience.
Was first to develop a tiny structure made from clusters of linked gold atoms that conducts electricity by allowing electrons to "hop" one at a time from cluster to cluster. Device would largely eliminate problem of heat buildup caused by flow of current in ultrasmall electrical devices.
Has developed tiny "wires" -- 100 times smaller than the wires commonly used in silicon chips -- capable of conducting current.
Research includes semiconductor physics, nanotechnology, traveling wave interactions and quantum electronics.
Directs Purdue-based research center focusing on developing new mixtures of pavement materials and procedures to test mixtures for durability and reliability. Center was first of five regional centers created by Federal Highway Administration in 1995.
Research includes smart materials processing, electroceramics and high-temperature superconductors. Has been involved in science and technology policy development and research planning and management within industry and government. Serves on the Department of Commerce Board of Overseers for the Malcolm Baldridge National Quality Award.
Has researched and consulted with industry on metal and materials production, processing and technology, including superconducting materials. Has developed and used X-ray instrumentation and techniques, such as diffraction and crystallography, to study structure of materials. Heads Purdue X-ray facility that conducts microstructural analysis of materials. Directs national effort to increase awareness of careers in materials science and engineering.
Winner of numerous teaching awards. Research includes using boiling liquid to remove heat from electronics and avionics. Developed computer-based method to uniformly cool aluminum parts after they've been formed from hot metal.
Research involves molecular beam epitaxy, or MBE, a technique used to build semiconductor materials layer by layer, allowing researchers to create new microelectronic devices. First to develop semiconductor lasers that operate in the blue-green area of the spectrum, rather than red and infrared, making practical their use in consumer and high-tech electronics from flat-screen TVs and computers to longer-playing CDs. Internationally known for expertise in surface acoustic wave devices, diluted magnetic semiconductor superlattices and quantum-well structures using MBE-grown dilute magnetic semiconductors.
Is a fellow of the Institute of Electrical and Electronics Engineers. Has published six books and more than 200 professional articles on the design and fabrication of integrated circuits. Has 10 patents. Uses epitaxial methods to fabricate semiconductors.
Is director of research center that develops semiconductor materials suitable for new types of electronic and optoelectronic devices, such as transistors, lasers, light-emitting diodes, high-speed optical detectors and optical storage technologies. Developed a method that uses light to probe the electrical properties of semiconductors. Expert in development and commercial applications of gallium arsenide technology. Is former research staff member and fellow of the IBM Watson Research Center. Has extensive experience with media. Is inventor of high-efficiency solar cell used by NASA on new generation of space vehicles. Is member of the National Academy of Engineering.
