Quick-Change Materials Break Silicon Speed Limit for Computers

Quick-Change Materials Break Silicon Speed Limit for Computers

Faster, smaller, greener computers, capable of processing information up to 1,000 times faster than currently available models, could be made possible by replacing silicon with materials that can switch back and forth between different electrical states.   The present size and speed limitations of computer processors and memory could be overcome by replacing silicon with [...]

Beyond Silicon: Next Generation Electronic Device

Beyond Silicon: Next Generation Electronic Device

In the consumer electronics industry, the mantra for innovation is higher device performance/less power. Arun Thathachary, a Ph.D. student in Penn State’s Electrical Engineering Department, spends his days and sometimes nights in the cleanroom of the Materials Research Institute’s Nanofabrication Laboratory trying to make innovative transistor devices out of materials other than the standard semiconductor [...]

Mystery of the Printed Diode Solved

Mystery of the Printed Diode Solved

For thirteen years the mystery has remained unsolved, but now Negar Sani, PhD student at Linköping University’s Laboratory of Organic Electronics, has succeeded in explaining how a printed diode can function in the GHz band. The diode forms the missing link between mobile phones and printed labels. With an article published in the Proceedings of [...]

Magnetic Vortices for Nanoscale Antennas

Magnetic Vortices for Nanoscale Antennas

Scientists at the U.S. Department of Energy’s Brookhaven National Laboratory are seeking ways to synchronize the magnetic spins in nanoscale devices to build tiny yet more powerful signal-generating or receiving antennas and other electronics. Their latest work, published in Nature Communications, shows that stacked nanoscale magnetic vortices separated by an extremely thin layer of copper [...]

New Materials, Electronics Dissolve When Told To

New Materials, Electronics Dissolve When Told To

A medical device, once its job is done, could harmlessly melt away inside a person’s body. Or, a military device could collect and send its data and then dissolve away, leaving no trace of an intelligence mission. Or, an environmental sensor could collect climate information, then wash away in the rain.   It’s a new [...]
