Imec reports for the first time selective chemical vapor deposition (CVD) of GeSn in a production-like environment using commercially available Ge and Sn precursors. The resulting GeSn layers with 8% Sn are defect free, fully strained and thermally stable for temperatures up to 500 C. This technique is used to implement uniaxial compressive stress in a Ge channel, the key method for reaching very high mobility values in MOSFETs.
Researchers from the London Centre for Nanotechnology and the Physics Department of Sapienza University of Rome have discovered a technique to 'draw' superconducting shapes using an X-ray beam. This ability to create and control tiny superconducting structures has implications for a completely new generation of electronic devices.
Yoshiyuki Miyamoto from the Dynamic Process Simulation Group at the the Nanosystem Research Institute of the National Institute of Advanced Industrial Science and Technology (AIST), has performed the first-principles simulations that consistently treat from optical excitation to electron-hole splitting in a photovoltaic material formed by molecules having different electron affinities.
The LOASIS program at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has already demonstrated high-quality beams up to a billion electron volts in a mere 3.3 centimeters; the BELLA project will reach 10 billion electron volts in a single meter.
Rice University researchers have created a solid-state, nanotube-based supercapacitor that promises to combine the best qualities of high-energy batteries and fast-charging capacitors in a device suitable for extreme environments.
Surprisingly, transmitting information-rich photons thousands of miles through fiber-optic cable is far easier than reliably sending them just a few nanometers through a computer circuit. However, it may soon be possible to steer these particles of light accurately through microchips thanks to new research.
Forscher haben gezeigt, dass Spinstroeme mit Schallwellen erzeugt werden koennen. Weiterhin fanden sie, dass Spinstroeme auf isolierenden nichtmagnetischen Substraten auch durch einen weiteren Effekt, den sogenannten langreichweitigen Spin-Seebeck-Effekt erzeugt werden koennen.
