From: Nanoscale visualization and spectral fingerprints of the charge order in ScV6Sn6 distinct from other kagome metals

Fig. 1

a The schematic of the bulk crystal structure of ScV6Sn6, and (b) ab-plane surface atomic structure. c Topographic linecut showing single steps between consecutive Sn2 terraces taken along the red line in the inset. Inset in c shows an STM topograph spanning several consecutive steps. d Magnetization measurements (zero-field cooled, then taken at 1 T applied in the ab-plane warming up) showing a kink at T* associated with the bulk transition. STM topographs of (e) Sn2 termination and (g) kagome termination, and (f, h) associated Fourier transforms. Atomic Bragg peaks are circled in black; CO peaks are enclosed in green circles, red squares and blue triangles. STM setup conditions: (c) Iset = 10 pA, Vsample = 1 V; (e) Iset = 400 pA, Vsample = 20 mV; (g) Iset = 200 pA, Vsample = 200 mV. Scale bars correspond to: (e, g) 4 nm; (f, h) 1 Å−1.
