The ability to print the PARC plastic transistors on flexible substrates may allow manufacturers to produce electronic "paper" and computer displays that roll up like a window shade.

Not quite, but close. In a breakthrough for low-cost electronics manufacturing, researchers at Palo Alto Research Center (PARC), a Xerox subsidiary, have successfully created a transistor array of the type used to control a flat-panel display using a modified ink-jet printer and semiconductor "ink." Still under development, the technique is expected to dramatically lower the cost of the popular displays by replacing more expensive photolithography techniques that dominate display manufacturing. The new technology, co-funded by the National Institute of Standards and Technology (NIST), is expected to work on either rigid or flexible substrates, and could create whole new opportunities for wall-sized TVs, unbreakable cell phone displays, computer displays that could roll up like a window shade and electronic paper.
PARC researchers used a new polymer-based semiconductor ink from Xerox Research Center Canada (XRCC) to build a prototype flat-panel display circuit. Transistor arrays are complex devices with multiple layers of conductors, insulators and semiconductors. Conventional photolithography uses a multistep process for each layer, first laying down the appropriate material, then creating a pattern for the components, and finally etching or transferring the pattern to the material. By contrast, PARCs ink-jet process patterns and prints the components of each layer of the transistor array in one step. A key innovation, according to PARC, was a computer-vision system that ensures precise registration of each layer even if the substrate deforms slightly during the process.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
