摘要
对NbSe3在第一相变温度上下的隧道谱测量,意外地发现在通过电荷密度波(CDW)相变温度时电子态密度没有反常.
Tunneling spectra of NbSe 3 between 77K and room temperature have been measured.A charge density wave (CDW) pseudogap exists up to a temperature higher than ~260K.While the gap parameter undergoes an accelerated change between ~130 and ~160 K,the junction conductance at zero bias does not show any anomaly around T 1 =145K,the upper CDW transition temperature.
