Quantum well states in ultrathin Bi films: Angle-resolved photoemission spectroscopy and first-principles calculations study

Quantum well states (QWSs) in ultrathin Bi(001) films grown on $\mathrm{Si}(111)\ensuremath{-}7\ifmmode\times\else\texttimes\fi{}7$ with thicknesses up to several tens of nanometers were studied by angle-resolved photoemission spectroscopy and first-principles calculations. We observed QWSs at vario... View More
