Emptying Dirac valleys in bismuth using high magnetic fields
Materials in large magnetic fields can be driven into the quantum limit, where electrons occupy only the lowest Landau level and the response is determined by interactions. Here the authors go beyond this limit by emptying one or two of bismuth’s electronic valleys, depending on the field direction....

| Sumario: | Materials in large magnetic fields can be driven into the quantum limit, where electrons occupy only the lowest Landau level and the response is determined by interactions. Here the authors go beyond this limit by emptying one or two of bismuth’s electronic valleys, depending on the field direction. |
