Researchers at Sandia National Laboratories developing ultraviolet (UV) light-emitting diodes (LEDs) recently demonstrated two deep UV semiconductor optical devices that set records for wavelength/power output. One emits at a wavelength of 290 nm and produces 1.3 milliwatts of output power, and the other emits at a wavelength of 275 nm and produces 0.4 milliwatts of power.
Engineers at Princeton University and Hewlett-Packard have invented a combination of materials that could lead to inexpensive, compact electronic memory devices for archiving digital images or other data.
Physicists have discovered a mechanism that forces sharp edges on the surface of a silicon crystal to become rounded, and have described this rounding in detail for the first time
Engineers have designed a new diode that transmits more electricity - conducting 150,000 A per square centimetre. Unlike other diodes in its class, called tunnel diodes, the new diode is compatible with silicon, so manufacturers could build it into mainstream electronic devices such as mobile phone and computers.
Silicon, one of the base elements of our planet, is the foundation of the modern information society. Modern electronics would be unthinkable without the development of silicon transistors
The Storage Networking Industry Association (SNIA) has approved the formation of SNIA (Australia and New Zealand) Ltd as a regional affiliate. The organisation will develop educational and marketing programs to promote the use of storage networking solutions to IT professionals via the working together of vendors, developers and integrators.
Epson is developing a ferroelectric material for ferroelectric random-access memory (FeRAM), a next generation type of memory. The new material has been tentatively named PZTN.
Combine the reliable, rotational position feedback of Celesco's two wire, 4-20 mA current loop signal with the linearity and resolution of a plastic-hybrid potentiometer, than package it in stainless steel sealed to IP68 submersible standards, and the result is an accurate and safe RT9420 sensor.
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.
