System Bits: Jan. 29


Quantum physics make hybrid semiconductors glow Hybrid semiconducting materials have quantum properties capable of bringing significant changes to light-emitting diode lighting and monitors, along with photovoltaic solar cells, researchers at the Georgia Institute of Technology report. Physical chemists worked with halide organic-inorganic perovskite (HOIP), which combines a crystal lattice wi... » read more

Optical memory Researchers at the University of Oxford, University of Exeter, and University of Münster propose an all-optical memory cell that can store more optical data, 5 bits, in a smaller space than was previously possible on-chip. The optical memory cell uses light to encode information in the phase change material Ge2Sb2Te5. A laser causes the material to change between ordered and... » read more

Can Graphene Be Mass Manufactured?


Since the isolation of graphene in 2004, the high mobility and unique transport properties of 2-dimensional semiconductors have tantalized physicists and materials scientists. Their in-plane carrier transport and lack of dangling bonds potentially can minimize line/edge scattering and other effects of extreme scaling. While 2-D materials cannot compete with silicon at current device dime... » read more

Solar jet fuel Researchers at ETH Zurich demonstrated the ability to use solar energy to create the precursor to jet fuel from water and carbon dioxide, a process that could lead to carbon-neutral air travel. The scientists performed 295 consecutive cycles in a 4 kW solar reactor, yielding 700 standard liters of hydrogen and carbon monoxide (syngas), the precursor to kerosene and other liqu... » read more

Making high-capacity data caches more efficient

Optical communication on silicon chips With the huge increase in computing performance in recent decades achieved by squeezing ever more transistors into a tighter space on microchips, at the same time this downsizing has also meant packing the wiring within microprocessors ever more tightly together. This has led to effects such as signal leakage between components, which can slow down commun... » read more

Magnetic chips HRL Laboratories—an R&D venture between Boeing and General Motors—has been awarded a contract to develop a new class of magnetic integrated components. HRL has received the award from the Defense Advanced Research Project Agency (DARPA) under the Magnetic, Miniaturized, and Monolithically Integrated Components (M3IC) program. The goal is to develop new magnetic materials... » read more
