准一维K0 3 MoO3 蓝青铜中的电荷密度波(CDW)失稳一直是凝聚态物理研究的热点之一。在 180K温度附近K0 3 MoO3 发生晶格畸变伴随着电荷发生空间周期性调制 ,形成所谓的CDW。当调制波矢量q =2KF 时 ,布里渊区将与费米面套叠而打开一个Peierls能隙 ,导致体系从导体向半导体或绝
The instability of charge density wave (CDW) in quasi-one-dimensional K0 3 MoO3 blue bronze has always been one of the hot topics in condensed matter physics research. The lattice distortion of K0 3 MoO3 occurs near the 180K temperature with the spatial periodic modulation of charges, forming the so-called CDW. When modulating the wave vector q = 2KF, the Brillouin zone will be nested with the Fermi surface to open a Peierls energy gap, resulting in a system from the conductor to the semiconductor or never
