A voltage-controlled topological spin switch for ultralow-energy computing


Research led by Shaloo Rakheja, Professor of Electrical and Computer Engineering at NYU Tandon.

Magnetic based technologies, like NanoMagnetic Logic, are gaining more interest as possible substitutes of CMOS transistors. Most of the logic and memory devices use nanomagnetic mechanisms to store and manipulate information. They needed energy only for reading and writing the information, not for maintaining their magnetic state…researchers from New York University introduce a voltage-controlled topological spin switch (vTOPSS). Instead of the current, it requires an electric field to switch between two Boolean logic states. This could reduce the heat generated and the energy used.
