Why silicon crystals lose their 'edge'

05 November, 2003

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


Rail-to-rail op amp

28 October, 2003 | Supplied by: Soanar Limited

Linear Technology has released the LT6011, a dual micropower precision rail-to-rail output op amp.


Diode developed for faster electronics

14 October, 2003

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.


Breakthrough in silicon photonics

05 October, 2003

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


Formation of storage networking association

22 September, 2003

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.


Wireless LAN PC

09 September, 2003 | Supplied by: Helios Power Solutions

The AMT-N5568A is a fully sealed display and computing system enclosure that houses a single board computer with a Tillamook 266 MHz CPU.


Faster FeRAM on the way

03 September, 2003

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.


Secure microcontroller

11 August, 2003 | Supplied by: Braemac Pty Ltd

Atmel is sampling a secureAVR RISC microcontroller with 32 Mega-bit flash based on the AT90SC3232CS (secureAVR processor, 32 KB flash, 32 KB EEPROM) with in addition, 32 Mega-bit of flash for secure datastorage.


Rotational transducer

11 August, 2003 | Supplied by: IDM Instruments

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.


New manufacturing technique for microelectronics

24 July, 2003

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.


New approach to solid-state lighting

17 July, 2003

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.


DC bus converter chip set

07 July, 2003 | Supplied by: International Rectifier

International Rectifier has unveiled the first group of products in the family of DC bus converter chip sets for 48 V input and 150 W board-mounted power converters used in telecom and networking systems.


Buck MOSFET chip

07 July, 2003 | Supplied by: Soanar Plus

International Rectifier has introduced the IRF7821 and IRF7832 synchronous buck converter chip set designed to increase battery life in notebook computers.


Triple-Gate transistor from research to development

25 June, 2003

Intel has announced details of its 'tri-gate' transistor design, stating that the tri-gate transistor is moving from research to the development phase.


Silva attracted by magnetics group

19 June, 2003

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.
