Researchers with the US Department of Energy's Lawrence Berkeley National Laboratory (Berkely Lab) and the University of California at Berkeley have shown that for nanocrystals, the doping process in which one type of positively charged atom, or cation, is exchanged for another, takes place at a much faster rate than for crystals of extended size and is fully reversible, something that is virtually forbidden in micro-sized crystals under the same environmental conditions.
International Rectifier has introduced radiation-hardened (RAD-Hard) logic-level gate drive MOSFETs designed to boost efficiency and performance in circuits that traditionally relied on bipolar transistors.
Worldwide semiconductor revenue growth is starting to slow in the second half of 2004. Although the slowing will affect income mainly during the fourth quarter, the second half of 2004 is still generating strong growth of 10% on top of the increase seen in the first six months of the year, according to a newly-revised outlook from iSuppli's Electronic Components Forecast service.
An engineer at Sheffield University in Britain is leading a project that could revolutionise the way scientists, medics and others see the world - by allowing the earlier detection of cancer, the instant analysis of medical screening tests, and permitting the emergency and security services to work effectively in murky surroundings.
AMD says it is achieving a smooth transition to 90 nm manufacturing and has distributed low-power 90 nm Mobile AMD Athlon 64 processors for thin and light notebooks (previously codenamed 'Oakville'.
Maxim has introduced the MAX8720 step-down controller, featuring dynamically adjustable output, ultra-fast transient response, high DC accuracy and the high efficiency required for CPU-core power supplies.
