Vacancies may lead to atomic circuits
David Muller, assoc prof of applied and engineering physics, inserts a sample into the scanning transmission electron microscope (STEM) in his Duffield Hall laboratory
[ + ]Dealing with the state of isolation
When we think isolation in the electronics context, we think of the transformer. Magnetic fields transfer information without an electrical connection between primary and secondary windings creating the isolation barrier
[ + ]Does internal resistance reveal battery capacity?
During the last 20 years, three basic battery rapid test methods have emerged. All methods are resistance based, a characteristic that reveals the battery's ability to deliver load current
[ + ]Get rid of harmonics before they cost you money
This short technical note is about minimising harmonics; yet there will be those who don't as yet realise the extent to which harmonics cost money
[ + ]Memory roadmap shows the way
Semiconductor manufacturers are busily trying to anticipate what the future market will demand of them. Toshiba is just one company that is looking into the future and it has outlined what it sees in its latest 'strategic memory roadmaps'
[ + ]Brighter outlook for PolyLEDs
Scientists at Philips have developed new methods to significantly increase the efficiency of PolyLED polymer OLED displays. This opens the way to lower power consumption and will further strengthen the advantages of polymer OLED
[ + ]Rating power amplifiers for RF immunity testing
Over the years, tutorials have appeared in EMC journals explaining how to estimate the power required from a power amplifier intended for use in an RF immunity test system. Little material has explored the issue of gain compression in RF power amplifiers
[ + ]A memory to replace memory
Magnetoresistive random access memory (MRAM) is a memory technology that can potentially replace today's semiconductor memory technologies. The increasing capability of electronic devices is driving a growing need for increased memory performance
[ + ]Don't be afraid of lead-free soldering!
On July 1, 2006 lead-free soldering finally becomes law for the manufacturers and suppliers of electronic components in Europe. Many small and medium sized companies but also large industrial producers feel left alone with the changes to come
[ + ]Putting manufacturers to the test
Arc faults within low voltage (LV) switchgear have been potentially life threatening for many years. But in 1996, users were presented with a new standard of safety
[ + ]Researchers put a spin on electronics
University of Utah physicists have taken an important step towards a new generation of faster, cheaper computers and electronics by building the first 'organic spin valves'
[ + ]Prolonging the life of silicon
Engineers at Ohio State University have looked at the interface between layers of silicon and other materials in electronic devices. What they have learned may help traditional microelectronics remain vital to industry longer than most experts expect
[ + ]Technology beats transistor heat
Intel has identified new materials to replace those that have been used to manufacture chips for more than 30 years. This is a significant accomplishment as the industry races to reduce electrical current leakage in transistors
[ + ]The story behind the battery
One of the most remarkable and novel discoveries in the last 400 years has been electricity. You may ask, "Has electricity been around that long?" The answer is yes, and perhaps much longer
