In a paper published by Nano Energy, a team from Surrey's Advanced … [Read more...] about Implantable biosensor operates without batteries

KAIST physicists described a route to design the energy-efficient generation, manipulation and detection of spin currents using nonmagnetic two-dimensional materials. The research team, led by Professor Sungjae Cho, observed highly efficient charge-to-spin interconversion via the gate-tunable Rashba-Edelstien effect (REE) in graphene heterostructures. This research paves the … [Read more...] about Highly efficient charge-to-spin interconversion in graphene heterostructures

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

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

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
