Abstract

Read online

The electronic surface states of bismuth present promise for applications exploiting spin and valley degrees of freedom however their study is inhibited by bulk states. Here, the authors directly access the surface-state Landau levels of ultrathin bismuth films under a perpendicular magnetic field.
