Move Over, Silicon: A New Circuit in Town

Move Over, Silicon: A New Circuit in Town

When it comes to electronics, silicon will now have to share the spotlight. In a paper recently published in Nature Communications, researchers from the USC Viterbi School of Engineering describe how they have overcome a major issue in carbon nanotube technology by developing a flexible, energy-efficient hybrid circuit combining carbon nanotube thin film transistors with [...]

Charging Portable Electronics in 10 Minutes

Charging Portable Electronics in 10 Minutes

Researchers at the University of California, Riverside Bourns College of Engineering have developed a three-dimensional, silicon-decorated, cone-shaped carbon-nanotube cluster architecture for lithium ion battery anodes that could enable charging of portable electronics in 10 minutes, instead of hours.   Lithium ion batteries are the rechargeable battery of choice for portable electronic devices and electric vehicles. [...]

Playing Pool With Carbon Atoms

Playing Pool With Carbon Atoms

A University of Arizona-led team of physicists has discovered how to change the crystal structure of graphene, more commonly known as pencil ‘lead’, with an electric field, an important step toward the possible use of graphene in microprocessors that would be smaller and faster than current, silicon-based technology.   Graphene consists of extremely thin sheets [...]

Tiny Flexible Cell Phones to Print On Clothes?

Tiny Flexible Cell Phones to Print On Clothes?

A new version of “spaser” technology being investigated could mean that mobile phones become so small, efficient, and flexible they could be printed on clothing.   A team of researchers from Monash University’s Department of Electrical and Computer Systems Engineering (ECSE) has modelled the world’s first spaser (surface plasmon amplification by stimulated emission of radiation) [...]

Materials for Super-Efficient Nanoelectronics

Materials for Super-Efficient Nanoelectronics

Scientists at the Department of Energy’s SLAC National Accelerator Laboratory and Stanford University have discovered a potential way to make graphene — a single layer of carbon atoms with great promise for future electronics — superconducting, a state in which it would carry electricity with 100 percent efficiency.   Researchers used a beam of intense [...]

Graphene-Metal Sandwich Shrinks Electronics

Graphene-Metal Sandwich Shrinks Electronics

Researchers have discovered that creating a graphene-copper-graphene “sandwich” strongly enhances the heat conducting properties of copper, a discovery that could further help in the downscaling of electronics.   The work was led by Alexander A. Balandin, a professor of electrical engineering at the Bourns College of Engineering at the University of California, Riverside and Konstantin [...]

Thinnest LEDs Stronger, More Energy Efficient

Thinnest LEDs Stronger, More Energy Efficient

Most modern electronics, from flat-screen TVs and smartphones to wearable technologies and computer monitors, use tiny light-emitting diodes, or LEDs. These LEDs are based off of semiconductors that emit light with the movement of electrons. As devices get smaller and faster, there is more demand for such semiconductors that are tinier, stronger and more energy [...]

First Single-Molecule LED Created

First Single-Molecule LED Created

The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: a team led by the Institut de Physique et de Chimie des Matériaux de Strasbourg (IPCMS, CNRS/Université de Strasbourg), in collaboration with UPMC and CEA, has developed the first ever single-molecule LED. The device is formed from a single [...]

Natural 3-D Counterpart to Graphene Discovered: New Form of Quantum Matter

Natural 3-D Counterpart to Graphene Discovered: New Form of Quantum Matter

The discovery of what is essentially a 3D version of graphene — the 2D sheets of carbon through which electrons race at many times the speed at which they move through silicon — promises exciting new things to come for the high-tech industry, including much faster transistors and far more compact hard drives. A collaboration [...]
