The findings could revolutionize electronics and quantum computing. A breakthrough in a topological insulator material, which possesses insulating properties internally but conductive properties on the surface, has the potential to transform the realms of advanced electronics and quantum computing,
A new method to control quantum states in a material is shown. The electric field induces polarization switching of the ferroelectric substrate, resulting in different magnetic and topological states. Credit: Mina Yoon, Fernando Reboredo, Jacquelyn DeMink/ORNL, U.S. Dept.
“The research could result in many practical applications, such as next-generation electronics, spintronics, and quantum computing,” said ORNL’s Mina Yoon, who led the study. Such matter could lead to high-speed, low-power electronics that burn less energy and operate faster than current silicon-based electronics. The ORNL scientists published their findings inReference: “Non-volatile electric control of magnetic and topological properties of MnBi2Te4 thin films” by Wei Luo, Mao-Hua Du, Fernando A Reboredo and Mina Yoon, 28 April 2023,
