Kagome superconductor has attracted enormous interests because it is considered to be a good platform to studied the interplay between electronic correlation, band topology, unconventional superconductivity, charge/spin density wave and son on. In this talk I would like to talk about crystal growth and physical property manipulation of Kagome superconductor AV3Sb5 (A = K, Rb and Cs) and other related materials. Firstly, I will briefly introduce some basic knowledge about crystal growth, and then demonstrate the different types of quantum materials grown by our group in recent years. In the second part, I will focus on the novel physical properties in CsV3Sb5, including chiral charge order, nematic superconductivity; following by how to manipulation the charge density wave and superconductivity by chemical doping. Finally, I will show some new results on exploration of new Kagome superconductors.
