Charging Power of Quantum Batteries


New technical paper titled "Quantum Charging Advantage Cannot Be Extensive Without Global Operations" from researchers at Institute for Basic Science (IBS) and Seoul National University. Abstract "Quantum batteries are devices made from quantum states, which store and release energy in a fast and efficient manner, thus offering numerous possibilities in future technological applications... » read more

What Quantum Batteries Have in Store


Quantum battery technology is approaching an inflection point similar to the one quantum computing crossed a decade or so ago, escalating it from a theoretical curiosity to an engineering challenge worth solving. Quantum batteries exploit the strange physical laws of the very small — the quantum world — to gain performance advantages over classical batteries. Recent research on charging ... » read more

Technical Paper Round-Up: March 22


New memories, materials, and transistor types, and processes for making those devices, highlighted the past week's technical papers. That includes everything from vertical MoS2 to programmable black phosphorus image sensors and photonic lift-off processes for flexible thin-film materials. Papers continue to flow from all parts of the supply chain, with some new studies out of Pakistan, Seoul... » read more

An Energy-Efficient DRAM Cache Architecture for Mobile Platforms With PCM-Based Main Memory


Abstract "A long battery life is a first-class design objective for mobile devices, and main memory accounts for a major portion of total energy consumption. Moreover, the energy consumption from memory is expected to increase further with ever-growing demands for bandwidth and capacity. A hybrid memory system with both DRAM and PCM can be an attractive solution to provide additional capacity ... » read more

Power/Performance Bits: July 25


Sodium-ion cathode Researchers at the University of Texas at Dallas and Seoul National University developed a manganese and sodium-ion-based cathode material they hope could lead to lower-cost rechargeable batteries. In a typical lithium-ion battery, the cathode is made of lithium, cobalt, nickel and oxygen. "Lithium is a more expensive, limited resource that must be mined from just a fe... » read more

Materials For Future Electronics


Examining the research underway in electronics materials provides a keyhole view into what may be possible in future electronics design. Although some of this research will not end up in commercial products, it does provide an indication of the kinds of problems that are being addressed, how they are being approached, and where the research dollars are being spent. Flexible electronics are a... » read more

Power/Performance Bits: June 16


Lighting up graphene A team of scientists from Columbia University, Seoul National University, and Korea Research Institute of Standards and Science demonstrated an on-chip visible light source using graphene as a filament. They attached small strips of graphene to metal electrodes, suspended the strips above the substrate, and passed a current through the filaments to cause them to heat up.... » read more
