Extended Data Fig. 1: Cs clustering on as-cleaved Sb-terminated surface.
From: Cascade of correlated electron states in the kagome superconductor CsV3Sb5
(a) 3D portrayal of a large-scale morphology of the Sb layer from an STM topograph. Inset is a 3D zoom-in of a small square region covering three Cs atoms. (b) As-cleaved STM topograph with several Cs atoms scattered on the surface. The apparent height of Cs atoms in (b) is approximately 2 Angstroms, and the color scale is saturated to emphasize the 4a0-CO modulation. STM setup condition: (a) Vsample = 200 mV, Iset = 10 pA; (b) Vsample = 200 mV, Iset = 50 pA. T = 4.5 K in all panels.
