Moriches researcher receives national award: Studies nuclear fusion and the sun: How long will it shine?
Chemist Richard L. Hahn of Moriches, N.Y., will be honored on March 28 by the world's largest scientific society for his work with solar neutrinos, high-speed particles from which researchers learn about the sun and nuclear fusion. He will receive the American Chemical Society Award for Nuclear Chemistry at the Society's national meeting in San Francisco. (2000-03-20)

New semiconductor alloy's 'crazy physics' makes it a possible photovoltaic power source for satellites
Scientists at the Department of Energy's Sandia National Laboratories are researching ways to use a new semiconductor alloy, indium gallium arsenide nitride (InGaAsN), as a photovoltaic power source for space communications satellites and for lasers in fiber optics. (2000-03-08)

Tougher Than Silicon
A rugged, powerful new breed of semiconducting devices may be possible with a new alloy of silicon-carbide and germanium developed by scientists at the University of Delaware. (1999-05-10)

Jumping Atoms At The Surface Of A Metallized Semiconductor
Physicists Alexei Glebov and Stefan Vollmer in the group of Professor Peter Toennies at the Max Planck Institute for Fluid Dynamics in Goettingen have succeeded in gaining the first insight into the dynamical behavior of single adatoms on a semiconductor surface at temperatures close to its melting point (Physical Review Letters, 19 April 1999). (1999-04-28)

True Grit: "Sandpaper" Alloy May Suggest Rugged, Powerful New Devices, UD Researcher Reports
Sandpaper's cousin, silicon-carbide, may set the stage for a rugged, powerful new breed of semiconducting devices, a University of Delaware researcher will report April 6 during the Materials Research Society meeting. A new alloy of silicon-carbide and germanium might handle hot, high-power, high-frequency microelectronic and microelectromechanical (MEMS) devices better than silicon, James Kolodzey says. (1999-04-07)

Electronics Could Take A Quantum Leap
Physicists at DOE's Idaho National Engineering and Environmental Laboratory and Washington State University are firing positrons into quantum dots - particles 1/1,000th the diameter of a human hair - to characterize the size and electronic energy potential of the dot. Harnessing this energy by hooking several dots together could substantially enhance future electronics. (1999-03-18)

Gamma-Ray Spectrum Catalogues Released On Web
Researchers and scientists now have access to on-line reference standards developed at the Idaho National Engineering and Environmental Laboratory (INEEL). The updated Ge and original NaI(TI) Gamma-Ray Spectrum Catalogues, developed by the (1999-02-08)

UD Computer News: Future Looks Bright For Tunnel Diodes, Promising Faster, More Efficient Circuits
In the Oct. 12, 1998 issue of Applied Physics Letters, online Oct. 7, University of Delaware researchers--with scientists at the Naval Research Laboratory and Raytheon Systems Co.--describe (1998-10-01)

Defects Are The Spices For Semiconductors
Complete uniformity generates bland food; minute admixtures of spices provide tasty surprise and special quality. This statement holds even more strongly for semicounductors, our materials for modern electronics. The significance of defects in otherwise almost perfect solid materials is described by Hans J. Queisser (Max Planck Institute for Solid-State Research, Stuttgart, Germany) and Eugene E. Haller (University of California at Berkeley, USA) Science (vol. 281, 14 August 1998). (1998-08-20)

Little Tin Worms On The March
In high-end electronics, where success hinges on being lighter, faster, and smaller, size is the biggest barrier to progress. Researchers at Michigan Tech University have discovered little tin (1998-02-26)

Researchers Puzzle Over The Source Of Mysterious X-Rays Recorded Above The Earth
The flight of a balloon sent aloft by scientists over Kiruna, Sweden, seemed uneventful -- until researchers started examining the data. What was found by three graduate students has scientists scrambling for an explanation: an intense stream of X-rays, occurring in seven bursts, each separated by only a few minutes and lasting for a total of half an hour. The evidence is that the bursts came not from space, but from the Earth's upper atmosphere (1997-12-08)

Diamond Find: Carbon, Plus Germanium, Helps Silicon 'Shine,' UD Researchers Say
SEPT. 1, 1997--As computer makers scramble to marry high- speed optical technologies with conventional chips made of silicon--the cheap, sand-type material incapable of 'shining'--University of Delaware researchers today reported a silicon-based device that converts some light into electricity. The key seems to be carbon, the same element responsible for diamond, graphite and coal, according to an article in the new issue of IEEE Electron Device Letters. (1997-08-22)

Combining Two Types Of Transistors Results In Improved Circuits
Researchers at the University of Illinois have developed a method of combining two types of transistors in high- performance devices with a variety of applications, including wireless products and optical communications. (1997-07-15)

'Quantum Dots:' The Finish Line In High-Speed Computing?
In the full-throttle quest to make smaller, faster and better computer chips, University of Wisconsin-Madison engineer Max Lagally is exploring what may be the final frontier: Building them one atom at a time (1997-04-18)

Materials Science: UD Chemist Proposes New Description Of Reactions For "Growing" Computer Chips
University of Delaware research might someday help computer companies (1997-04-14)

ORNL's Colorful Nanocrystals Could Lead To Faster Computers
Using an accelerator, researchers at the Department of Energy's Oak Ridge National Laboratory can implant gold ions in high concentrations in glass surface layers, creating a variety of striking colors. The researchers also can control the microscopic behavior of the resulting nanocrystals, or clusters of several hundred metallic atoms each. (1996-09-20)
