About every 18 months, the number of transistors in computer chips doubles - the direct result of ever-shrinking sizes. By decreasing the size of these components and consequently, fitting more of them onto a single chip, computer speed and power improves. Thanks to a new manufacturing technique - developed by an international team of researchers which includes Paul Nealey, a University of Wisconsin-Madison chemical engineer - manufacturing the minute may soon be cheaper and more exact.
In a different approach to creating white light, several researchers at the Department of Energy's (DOE) Sandia National Laboratories have developed what is claimed to be the first solid-state white light-emitting device using quantum dots. In the future, the use of quantum dots as light-emitting phosphors may represent a major application of nanotechnology.
Intel has announced details of its 'tri-gate' transistor design, stating that the tri-gate transistor is moving from research to the development phase.
Magnets form the basis of computer technology, so the speed at which magnets can act and react has become extremely important. The Nanomagnetics and Spin Dynamics (NSD) group in the School of Physics recently hosted Dr Tom Silva, from the National Institute of Standards and Technology (NIST) in Colorado, to work with them on a development of a high speed magnetometer which measures magnetisation at very short time scales.
The ability to make atomic-level changes in the functional components of semiconductor switches, demonstrated by a team of Oak Ridge National Laboratory, North Carolina State University and University of Tennessee physicists, could lead to changes in the semiconductor industry.
The KBMS series of programmable relays is designed for machine automation and process control. Several models are offered which provide a choice of input power (AC or DC), number of input/outputs (10, 12 and 20), and input type (digital DC or AC and 0-10 VDC analog).
A tiny solid-state light emitter produced by Phaedon Avouris and his colleagues at IBM, consists of a single-walled carbon nanotube (NT) strung between two electrodes and controlled by a third.
