Evolution of charge order in the hole-doped kagome superconductor CsV₃Sb₅

We present a study of charge density wave (CDW) orders with hole doping in the kagome lattice sites of CsV₃Sb₅, utilizing high dynamic range single crystal X-ray diffraction (SCXRD) measurements. Vanadium atoms are replaced with controlled amounts of Titanium atoms using a conventional flux-based single-crystal growth technique to achieve hole doping in the kagome sites. We examine the progression of charge correlations upon the suppression of long-range charge density wave order as the doping level transitions from the first superconducting dome to the second superconducting dome in CsV_3-xTi_xSb₅. Our data indicates that the 2×2×2 supercell is more robust than the 2×2×4 supercell, remaining stable at relatively higher Ti-doping levels. At a doping level of x = 0.15, within the region of the second superconducting dome, no superlattice peaks are detected, revealing a complete suppression of charge correlations. Our work reveals the intricate interplay between unconventional superconductivity and the charge density waves correlations with hole doping in the kagome sites of CsV₃Sb₅
