Researchers at New York University and IBM Research have demonstrated a new mechanism involving electron motion in magnetic materials that points to new ways to potentially enhance data storage. The work, reported in the journal Physical Review Letters, unveils a process for setting the direction of the magnetic information, or spin, based on an electrical current. The … [Read more...] about Research takes electrons for a spin in moving toward more efficient, higher density data storage
Efficient, 'green' quantum-dot solar cells exploit defects
Novel quantum dot solar cells developed at Los Alamos National Laboratory match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements that most solar cells of this type rely on. "This quantum-dot approach shows great promise for a new type of toxic-element-free, inexpensive solar cells that exhibit remarkable defect tolerance," said … [Read more...] about Efficient, 'green' quantum-dot solar cells exploit defects
Observation of intervalley transitions can boost valleytronic science and technology
An international research team led by scientists at the University of California, Riverside, has observed light emission from a new type of transition between electronic valleys, known as intervalley transmissions. The research provides a new way to read out valley information, potentially leading to new types of devices. Current semiconductor technology uses electronic charge … [Read more...] about Observation of intervalley transitions can boost valleytronic science and technology

Atomically thin magnets for next generation spin and quantum electronics
In 2005, Science asked if it was possible to develop a magnetic semiconductor that could work at room temperature. Now, just fifteen years later, researchers have developed those materials in two-dimensional form, solving one of science's most intractable problems. As our smartphones, laptops, and computers get smaller and faster, so do the transistors inside them that control … [Read more...] about Atomically thin magnets for next generation spin and quantum electronics
