A new milestone for light-driven electronics

https://phys.org/news/2023-01-milestone-light-driven-electronics.html

"excitons (electrically neutral quasiparticles) in topological insulator... light-driven computer chips and quantum technologies... topological insulators enable lossless conduction of electrical current and robust information storage... created excitons applying short light pulse to thin film of one layer atoms... excitons activated in topological insulator... could be used to generate qubits... bismuthene's heavy atoms make it topological insulator... at room temperature... could pave way for topological qubits"
