Figure 1

Sketch of energy bands of bulk Bi(111).

(a) LDA calculations and (b) ARPES results. Red bands are spin splitting surface states, S1 and S2. Black arrows indicate the spin polarization. Blue and green bands are bulk valence band and bulk conduction band. Dashed line in (b) indicates that no bulk conduction band has been detected in ARPES. The agreement between LDA and ARPES near the is poor.
