University of California - Santa Barbara A UCSB postdoctoral scholar in physics discovers a counterintuitive phenomenon: the coexistence of superconductivity with dissipation For his doctoral dissertation in the Goldman Superconductivity Research Group at the University of Minnesota, Yu Chen, now a postdoctoral researcher at UC Santa Barbara, developed a novel way to fabricate superconducting nanocircuitry. However, the extremely small zinc nanowires he designed did some unexpected —...

Researchers Create Light-trapping Nanostructure Using Genetic-inspired Approach
2014-06-16 03:26:13

University of Rochester Physicists at the University of Rochester have created a silicon nanocavity that allows light to be trapped longer than in other similarly-sized optical cavities. An innovative design approach, which mimics evolutionary biology, allowed them to achieve a 10-fold improvement on the performance of previous nanocavities. In a paper published in Applied Physics Letters today and featured on the cover, the scientists demonstrate they have confined light in a...

Researchers at the University of Notre Dame and Pennsylvania State University have announced breakthroughs in the development of tunneling field effect transistors (TFETs), a semiconductor technology that takes advantage of the quirky behavior of electrons at the quantum level. Transistors are the building blocks of the electronic devices that power the digital world, and much of the growth in computing power over the past 40 years has been made possible by increases in the number of...

Findings may impact next-generation handheld devices, solar arrays, and basic science Unexpected voltage increases of up to 25 percent in two barely separated nanowires have been observed at Sandia National Laboratories. Designers of next-generation devices using nanowires to deliver electric currents – including telephones, handheld computers, batteries and certain solar arrays – may need to make allowances for such surprise boosts. "People have been working on nanowires...

In an advance for nanoscale electronics, researchers at the National Institute of Standards and Technology (NIST) have demonstrated a new design for silicon nanowire transistors that both simplifies processing and allows the devices to be switched on and off more easily. The NIST design, described in a paper published June 29 by the journal Nanotechnology,* uses a simplified type of contact between the nanowire channel and the positive and negative electrodes of the transistor. The design...
