Extended Data Fig. 6: Bias dependence of STM topographs.
From: Cascade of correlated electron states in the kagome superconductor CsV3Sb5
(a-d) STM topographs acquired over an identical region at 60 K under different biases. (e-h) STM topographs acquired over another region at 4.5 K under different biases. Insets in (a-h) are the associated Fourier transforms. Green, brown and blue circles denote the atomic Bragg peaks, tri-directional charge order peaks and unidirectional stripe charge order peaks in momentum-transfer space, respectively. STM setup condition: (a) Vsample = 90 mV, Iset = 30 pA; (b) Vsample = 50 mV, Iset = 30 pA; (c) Vsample = −30 mV, Iset = 40 pA; (d) Vsample = −90 mV, Iset = 40 pA; (e) Vsample = 200 mV, Iset = 400 pA; (f) Vsample = 50 mV, Iset = 100 pA; (g) Vsample = 10 mV, Iset = 20 pA; (h) Vsample = −50 mV, Iset = 100 pA.
