A technical paper titled “Direct synthesis of nanopatterned epitaxial graphene on silicon carbide” was published by researchers at University of Technology Sydney, Ludwig-Maxilimians Universität München, Monash University, and Imperial College London. Abstract: "This article introduces a straightforward approach for the direct synthesis of transfer-free, nanopatterned epitaxial graphene... » read more

The speed limit of optoelectronics


Abstract "Light-field driven charge motion links semiconductor technology to electric fields with attosecond temporal control. Motivated by ultimate-speed electron-based signal processing, strong-field excitation has been identified viable for the ultrafast manipulation of a solid’s electronic properties but found to evoke perplexing post-excitation dynamics. Here, we report on single-photon... » read more

An achromatic X-ray lens


Abstract "Diffractive and refractive optical elements have become an integral part of most high-resolution X-ray microscopes. However, they suffer from inherent chromatic aberration. This has to date restricted their use to narrow-bandwidth radiation, essentially limiting such high-resolution X-ray microscopes to high-brightness synchrotron sources. Similar to visible light optics, one way t... » read more

Softbank To Buy ARM For $32.34B


By Ed Sperling & Ann Steffora Mutschler Japan's Softbank will acquire ARM for $32.34 billion, according to an agreement made public this morning. The deal has the backing of ARM's board of directors, which unanimously will recommend ARM shareholders approve it, according to a company statement. Under the terms of the deal, Softbank will at least double employee headcount in the United... » read more

System Bits: Oct. 14


Exotic states of light and matter In research that merges two areas that have only been studied separately, ETH researchers are studying solid-state physics and quantum optics as a potential first step toward quantum computing. Specifically, the physicists are looking between tiny mirrors to a special layer of the semiconductor material gallium arsenide, prepared in such a way that the elec... » read more

Origami-Shaped Antennas A Georgia Tech-led research team is working to develop a unique approach to making extremely compact and highly efficient antennas and electronics based on principles derived from origami paper-folding techniques to create complex structures that can reconfigure themselves by unfolding, moving and even twisting in response to incoming electromagnetic signals. The str... » read more

Thinking Small


By Barry Pangrle “But I am not afraid to consider the final question as to whether, ultimately—in the great future—we can arrange the atoms the way we want; the very atoms, all the way down! What would happen if we could arrange the atoms one by one the way we want them (within reason, of course; you can't put them so that they are chemically unstable, for example). — Richard Feynman, ... » read more
