Scientists predict the existence of flat electronic bands at the Fermi level, a finding that could enable new forms of quantum computing and electronic devices.
June 19, a team of scientists led by Rice University's Qimiao Si predicts the existence of flat electronic bands at the Fermi level, a finding that could enable new forms of quantum computing and electronic devices.
"Most flat bands are located far from the Fermi energy, which limits their impact on the material's properties," said Si, the Harry C. and Olga K. Wiess Professor of Physics and Astronomy at Rice. These bands are especially sought after in transition metal ions called d-electron materials with specific crystal lattices, where they often show unique properties, Si said.
"Quantum interference can enable the Kondo effect, allowing us to make significant progress," said Lei Chen, a Ph.D. student at Rice. The study also highlights the potential for these materials to be very responsive to external signals and capable of advanced quantum control. The results indicate that the flat bands could lead to strongly correlated topological semimetals at relatively low temperatures potentially operating at high temperatures or even room temperature.
