Efficient Spin-Orbit Torque Switching with Non-Epitaxial Chalcogenide Heterostructures


Abstract: "The spin–orbit torques (SOTs) generated from topological insulators (TIs) have gained increasing attention in recent years. These TIs, which are typically formed by epitaxially grown chalcogenides, possess extremely high SOT efficiencies and have great potential to be employed in next-generation spintronics devices. However, epitaxy of these chalcogenides is required to ensure the... » read more

Coupling photons with electrons With the potential to lead to the creation of materials whose electronic properties could be “tuned” in real time simply by shining precise laser beams at them, researchers at MIT have produced and measured a coupling of photons and electrons on the surface of an unusual type of material called a topological insulator. This type of coupling had been predicte... » read more
