Nanoscientist Jimmy Xu Named AAAS Fellow
Brown University nanoscientist Jimmy Xu is one of five Brown faculty members awarded this year with the distinction of fellow from the American Association for the Advancement of Science (AAAS), the largest general scientific society. Xu, whose interests include nanoscale science and technology, quantum photonics, aperiodic optics, semiconductor lasers, molecular electro-optics, and collective behaviors of large coupled systems, was recognized for his contributions to advances in laser science, nanotechnology and bionanoelectronics. His ongoing research includes carbon nanotube structures, physics, and applications; silicon lasers and subwavelength photonics; synthesis and nonlithographic fabrication and sciences of quantum arrays made from metals, superconducting, molecules and semiconductors; DNA conductivity; and the physics of redox processes in proteins and cells. Xu is the Charles C. Tillinghast Jr. ’32 University Professor in the division of engineering and professor of physics. He is one of 486 fellows chosen from the AAAS membership this year and joins four other Brown faculty members: visual neuroscientist David M. Berson, marine ecologist Mark D. Bertness, brain scientist John P. Donoghue, and cell biologist Susan A. Gerbi. New fellows were announced in the Dec. 19 issue of Science and will be honored during a formal ceremony at the AAAS annual meeting in Chicago in February.
- 1. The branch of physics that deals with the use of electrical energy to create or manipulate light waves, generally by changing the refractive index of a light-propagating material;
2. Collectively, the devices used to affect the intersection of electrical energy and light.
Compare with optoelectronics.
- The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
- The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
