Physicists induce high-temperature superconductivity in semiconductor with Scotch tape
An international team led by University of Toronto physicists has developed a simple new technique using Scotch poster tape that has enabled them to induce high-temperature superconductivity in a semiconductor ...
Magnetic topological insulators are 1,000 times more energy-efficient for switching
(Phys.org) —Topological insulators are an emerging class of materials that act as both insulators and conductors, and could potentially be used in smartphones, computers and other electronic devices.
Solving a mystery of thermoelectrics
Materials that can be used for thermoelectric devices—those that turn a temperature difference into an electric voltage—have been known for decades. But until now there has been no good explanation for ...
Vanadium oxide bronze: A replacement for silicon in microchips?
(Phys.org)—Few modern materials have achieved the fame of silicon, a key element of computer chips and the namesake for Silicon Valley, home to some of the world's most prominent technology firms.
Triple point: Physicists pinpoint key property of material that both conducts and insulates
It is well known to scientists that the three common phases of water – ice, liquid and vapor – can exist stably together only at a particular temperature and pressure, called the triple point.
Harnessing the potential of quantum tunneling: Transistors without semiconductors
(Phys.org) —For decades, electronic devices have been getting smaller, and smaller, and smaller. It's now possible—even routine—to place millions of transistors on a single silicon chip.

Reversible doping: Hydrogen flips switch on vanadium oxide
If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks ...
Using heat to make magnets
EPFL scientists have provided the first evidence ever that it is possible to generate a magnetic field by using heat instead of electricity. The phenomenon is referred to as the Magnetic Seebeck effect or ...
A novel platform for future spintronic technologies
Spintronics is an emerging field of technology where devices work by manipulating the spin of electrons rather than their charge. The field can bring significant advantages to computer technology, combining higher speeds ...
