Single-crystal X-ray diffraction characterization of CsCr3Sb5 and CsCr6Sb6 under high pressure and low temperature

The kagome lattice has attracted significant attention due to its unique electronic structures and strong correlation effects. Among these materials, CsCr3Sb5 and CsCr6Sb6 are a kind of newly discovered chromium-based kagome metals that exhibits intriguing quantum phenomena, including charge-density waves (CDW), spin-density waves (SDW), and unconventional superconductivity under pressure. Therefore, we propose conducting a Single-Crystal X-ray Diffraction (SCXRD) investigation of CsCr3Sb5 and CsCr6Sb6 up to 50 GPa under room temperature and 30K at ID15b. Our aim is to investigate pressure-induced structural transitions, with a focus on understanding how CDW order is suppressed and how unconventional superconductivity emerges under high pressure.
