Figure 2. QPI patterns of TSS on 30-BL Sb(111).

(a) Real-space dI/dV_b map in an area of 20 nm × 20 nm taken at V_b = 40 mV, I = 120 pA. (b) Fourier transform of (a), consisting of six strong peaks along . The first SBZ (yellow hexagon) and high symmetry directions are marked. (c) FT-STS pattern around with three observable scattering vectors q_A, q_Band q_C. It was taken on a 40 nm × 40 nm area at V_b = 20 mV. (d) Schematic of CEC as well as the spin texture around , which has a central electron pocket and six hole pockets. The small grey arrows represent the spin directions. q_Aand q_B are allowed scattering vectors, while q_C is low in probability and q_D totally forbidden.
