Power/Performance Bits: Jan. 11


Quantum dot transistors Researchers at Los Alamos National Laboratory and University of California Irvine used quantum dots to create transistors which can be assembled into functional logic circuits. "Potential applications of the new approach to electronic devices based on non-toxic quantum dots include printable circuits, flexible displays, lab-on-a-chip diagnostics, wearable devices, me... » read more

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

MRAM: from STT to SOT, for security and memory


Abstract: "Spin Transfer Torque Magnetic Random Access Memory (STT-MRAM) is one of the leading candidates for embedded memory convergence in advanced technology nodes. It is particularly adapted to low-power applications, requiring a decent level of performance. However, it also have interests for secured applications. The PRESENT cipher is a lightweight cryptographic algorithm targeting ultra... » read more

Switching a Perpendicular Ferromagnetic Layer by Competing Spin Currents


ABSTRACT "An ultimate goal of spintronics is to control magnetism via electrical means. One promising way is to utilize a current-induced spin-orbit torque (SOT) originating from the strong spin-orbit coupling in heavy metals and their interfaces to switch a single perpendicularly magnetized ferromagnetic layer at room temperature. However, experimental realization of SOT switching to date req... » read more
