Using laser light to trap atoms in a checkerboard-like pattern, a team led by Princeton scientists studied how resistance — the loss of electrical current as heat — can develop in unconventional metals. The results may help explain how certain types of superconductors made from copper oxides are able to conduct electricity so efficiently. The […]
A Valley So Low: Electrons Congregate In Ways That Could Be Useful To ‘Valleytronics’
A Princeton-led study has revealed an emergent electronic behavior on the surface of bismuth crystals that could lead to insights on the growing area of technology known as “valleytronics.” The term refers to energy valleys that form in crystals and that can trap single electrons. These valleys potentially could be used to store information, greatly […]
New Silicon Structure Opens The Gate To Quantum Computers
In a major step toward making a quantum computer using everyday materials, a team led by researchers at Princeton University has constructed a key piece of silicon hardware capable of controlling quantum behavior between two electrons with extremely high precision. The study was published Dec. 7 in the journal Science. The team constructed a gate that […]
Breakthrough Could Launch Organic Electronics Beyond Cell Phone Screens
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. The research, published Nov. 13 in the journal Nature Materials, focuses on organic semiconductors, a class of materials prized […]
Unusual Quantum Liquid On Crystal Surface Could Inspire Future Electronics
For the first time, an experiment has directly imaged electron orbits in a high-magnetic field, illuminating an unusual collective behavior in electrons and suggesting new ways of manipulating the charged particles. The study, conducted by researchers at Princeton University and the University of Texas-Austin was published Oct. 21, in the journal Science. The study demonstrates that […]
Underlying Connection Found Between Diverse Materials with Extreme Magnetoresistance
A new study from the Cava lab has revealed a unifying connection between seemingly unrelated materials that exhibit extreme magnetoresistance, the ability of some materials to drastically change their electrical resistance in response to a magnetic field, a property that could be useful in magnetic memory applications. “The chemistry of these materials looks completely different […]
Rice-Sized Laser, Powered One Electron at a Time
Princeton University researchers have built a rice grain-sized laser powered by single electrons tunneling through artificial atoms known as quantum dots. The tiny microwave laser, or “maser,” is a demonstration of the fundamental interactions between light and moving electrons. The researchers built the device – which uses about one-billionth the electric current needed to power […]
Photos of the Day: 3.5 Mile-High Martian Mound
Researchers based at Princeton University, the California Institute of Technology and Ashima Research suggest that Mars’ roughly 3.5-mile high Mount Sharp (above) most likely emerged as strong winds carried dust and sand into Gale Crater where the mound sits. If correct, the research could dilute expectations that the mound is the remnant of a massive […]
