University of California scientists working with a researcher from Washington State University at Los Alamos National Laboratorys Superconductivity Technology Center have developed a novel method for creating high performance, inorganic metal-oxide films using polymer-assisted deposition, or PAD. The breakthrough could pave the way for a greater use of metal-oxide films into the electronics manufacturing industry.
"The successful creation of both simple and complex metal-oxide films using PAD is part of the significance of this invention," said Dean Peterson, director of the Superconductivity Technology Center. "This technology provides a cost-effective approach to grow electronic and optical materials, which would find wide applications in any fields where the material is needed in the film form."
The PAD process uses a water-based solution to create a high-quality film of nearly any metal oxide. The films can be made from a single or several different metals with controlled atomic weight relationships. Amorphous, polycrystalline, or epitaxial films can be made with thicknesses from 10 nanometers to hundreds of nanometers or thicker. Using PAD, Los Alamos researchers have produced films of simple metal oxides, such as titanium dioxide and zinc oxide, and also complex metal oxides, such as strontium titanate and indium tin oxide.

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...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
