Extended Data Fig. 2: Determination of the local Ti concentration.
From: Unidirectional electron–phonon coupling in the nematic state of a kagome superconductor
a to d, Typical topographic images of CsV3-xTixSb5. The bright protrusions represent Ti atoms that replace V atoms in the underneath kagome layer. e to h, Distributions of Ti atoms in the field of view shown in a to d. The numbers of Ti atoms by counting are 172, 312, 913, and 1410, respectively. Set-point conditions: a: Vs = 1.5 V, It = 6 nA; b: Vs = 1.5 V, It = 4 nA; c: Vs = 1.5 V, It = 2 nA; d: Vs = 1.5 V, It = 5 nA.
