Infrared response of pure and W-doped K0.3MoO3
电荷密度波材料K0.3MoO3及W掺杂样品的红外光学响应的研究

We measured the reflectance spectra of pure,3% and 15% Tungsten\|doped K 0 3 MoO 3 below and above the charge density wave (CDW) transition temperatures.The conductivity spectra were derived from Kramers\|Kronig transformation.The effect of W impurities on phase phonons,single particle gap associated with CDW condensation were discussed.
