A discovery by an international team of researchers from Princeton University, the Georgia Institute of Technology and Humboldt University in Berlin points the way to more widespread use of an advanced technology generally known as organic electronics.
Germanium was the material of choice in the early history of electronic devices, and due to its high charge carrier mobility, it's making a comeback. It's generally grown on expensive single-crystal substrates, adding another challenge to making it sustainably viable for most applications. To address this aspect, researchers demonstrate an epitaxy method that incorporates van der Waals' forces to grow germanium on mica. They discuss their work in the Journal of Applied Physics.
A team of Hokkaido University researchers has developed a novel material synthesis method called proton-driven ion introduction (PDII) which utilizes a phenomenon similar to 'ion billiards.' The new method could pave the way for creating numerous new materials, thus drastically advancing materials sciences.
Nano-'hashtags' could be the key to generating the highly sought Majorana quasiparticle.
Red-sensitive, blue-sensitive and green-sensitive colour sensors stacked on top of each other instead of being lined up in a mosaic pattern -- this principle could allow image sensors with unprecedented resolution and sensitivity to light to be created. However, up to now, the reality hasn't quite met expectations. Researchers from Empa and ETH Zurich have now developed a sensor prototype that absorbs light almost optimally -- and which is also cheap to produce.
A research team from National University of Singapore has developed a soft, flexible and stretchable microfibre sensor for real-time healthcare monitoring and diagnosis. The novel sensor is highly sensitive and ultra-thin with a diameter of a strand of human hair. It is also simple and cost-effective to mass produce.
For the first time, physicists at MIT and Princeton University have developed a technique to visualize the behavior of electrons beneath a material's surface.
Since the late 60's electronic devices have stored and transmitted information (bits) in two-dimensional circuits. Now, researchers at the University of Cambridge have been able to break this barrier by creating a nanoscale magnetic circuit capable of moving information along the three dimensions of space. This breakthrough could lead to an important increase in storage and processing capacities of electronic devices over those used today.
Modern solar cells, which use energy from light to generate electrons and holes that are then transported out of semiconducting materials, have existed for over 60 years. Little attention has been paid, however, to the promise of using light to drive the transport of oppositely charged protons and hydroxides obtained by dissociating water molecules. Researchers report such a design, which has promising application in producing electricity to turn brackish water drinkable, Nov. 15 in Joule.
Emoticons, irregular spellings and exclamation points in text messages aren't sloppy or a sign that written language is going down the tubes -- these 'textisms' help convey meaning and intent in the absence of spoken conversation, according to newly published research from Binghamton University, State University of New York.
