摘要：

The charge-density-wave (CDW) phase transition in eta-Mo4O11 is studied by femtosecond time-resolved reflection. We observed coherent optical phonons in the reflectivity signal in both the normal and the CDW states. Below the transition temperature T-c1, six vibrational modes were clearly detected. Fear of them, centered at 64, 78, 85, and 98 cm(-1), were enhanced below T-c1. We conclude that the generation of these coherent phonon modes are closely related to the CDW state.
