ANIMATION Year after year, the explosive growth of computing power relies on manufacturers’ ability to fit more and more components into the same amount of space on a silicon chip. That progress, however, is now approaching the limits of the laws of physics, and new materials are being explored as […]

Credit: Yokohama National University Researchers from Yokohama National University in Japan have developed a prototype microprocessor using superconductor devices that are about 80 times more energy efficient than the state-of-the-art semiconductor devices found in the microprocessors of […]

: MIT researchers have found that an alloy material called InGaAs could be suitable for high-performance computer transistors. If operated at high-frequencies, InGaAs transistors could one day rival silicon. This image shows a solid state memory wafer traditionally made of silicon.

Researchers from the Centre of Excellence for Quantum Computation and Communication Technology (CQC2T) working with Silicon Quantum Computing (SQC) have located the ‘sweet […]

ANIMATION In a new realm of materials, PhD student Thanh Nguyen uses neutrons to hunt for exotic properties that could power real-world applications. Thanh Nguyen is in the habit of breaking down barriers. Take languages, for instance: Nguyen, a third-year doctoral candidate in nuclear science and engineering (NSE), wanted “to […]

Next-generation computer chip with two heads EPFL engineers have developed a computer chip that combines two functions — logic operations and data storage — into a single architecture, paving the way to more efficient devices. Their technology is particularly promising for applications relying on artificial intelligence. Credit: EPFL /LANES 2020 […]

Diamond could conduct electricity like metals when it is deformed to strains at the nanoscale, according to predictions from a study by an international team of scientists led by Nanyang Technological University, Singapore (NTU Singapore) and the Massachusetts Institute of Technology (MIT), USA. Using computer simulations, the team, which also […]

Researchers have discovered a way to transform the electronic properties of nanoscale needles of diamond. Credit: MIT News Normally an insulator, diamond becomes a metallic conductor when subjected to large strain in a new theoretical model. Long known as the hardest of all natural materials, diamonds are also exceptional thermal […]
