Transition metal silicides are promising for future developments in electronic devices, but fundamental aspects of the chemical bonding between their transition metal atoms and silicon remain poorly understood. One of the most important, but poorly known, properties is the strength of these bonds -- the thermochemical bond dissociation energy. Researchers from the University of Utah have investigated this, and in The Journal of Chemical Physics, they present their findings for a number of specific compounds.
Nothing is forever, but is it possible to slow down inescapable decay? An inquiry into the delay of deterioration of quantum memory devices and formation of black holes explained with intuitive analogies from everyday life
Nagoya University researchers probe a mysterious phase transition in an organic molecular conductor using synchrotron X-ray radiation.
A potential new state of matter is being reported in the journal Nature, with research showing that among superconducting materials in high magnetic fields, the phenomenon of electronic symmetry breaking is common.
EPFL scientists have developed a new method to efficiently measure electron transfer in dye-sensitized transition-metal oxide photovoltaics.
University of Groningen scientists led by physics professor Bart van Wees have created a graphene-based device, in which electron spins can be injected and detected with unprecedented efficiency. The result is a hundredfold increase of the spin signal, big enough to be used in real life applications, such as new spin transistors and spin-based logic. The research, part of the European Union's €1 billion Graphene Flagship, was published in Nature Communications on Aug. 15.
Rice University materials scientists replace all the atoms on top of a three-layer, two-dimensional crystal to make a transition-metal dichalcogenide with sulfur, molybdenum and selenium. The new material has unique electronic properties that may make it a suitable catalyst.
Chip makers appreciate what most consumers never knew: silicon's virtues include the fact that it 'rusts' in a way that insulates its tiny circuitry. Two new ultrathin materials share that trait and outdo silicon in other ways that make them promising materials for electronics of the future.
A research collaboration between the University of Illinois at Urbana-Champaign, the National Institute of Standards and Technology, and the University of Maryland has revealed a new technique by which scattering of sound waves from disorder in a material can be suppressed on demand. All of this, can be simply achieved by illuminating with the appropriate color of laser light.
Researchers have studied grain boundaries for decades and gained some insight into the types of properties grain boundaries produce, but no one has been able to nail down a universal system to predict if a certain configuration of atoms at grain boundaries will make a material stronger or more pliable. An interdisciplinary team of BYU researchers have cracked the code by juicing a computer with an algorithm that allows it to learn the elusive 'why' behind the boundaries' qualities.
