| 摘 要： | As the first magnetic kagome material to exhibit the charge density wave(CDW) order,FeGe has attracted much attention in recent research.Similar to AV3Sb5(A=K,Cs,Rb),FeGe exhibits the CDW pattern with an in-plane 2×2 structure and the existence of van Hove singularities near the Fermi level.However,sharply different from AV3Sb5 which has phonon instability at M point,all the theoretically calculated phonon frequencies in FeGe remain positive.Based on f...
