摘要
通过对有机材料(EDT-DSDTFVO)2FeCl4和(EDT-DSDTFVO)2GaCl4的输送测定,对其电阻率的温度依赖性以及压力效果进行了系统的比较,虽然两类盐的电阻率随着温度的变化行为十分相似,但是其压力效果尤其在高压时表现出明显的差异性。认为这种差异性和π-d相互作用密切相关。在这里,用EDT-DSDTFVO表示ethylenedithiodiselenadithiafulvalenothioquinone-1,3-dithiole methide。
We have done some systemic compare between the temperature dependence of the resistivity and its pressure effect by transportation determination of organic material （ EDT - DSDTFVO ） 2 FeCl4 and （ EDT - DSDTFVO） 2 GaCl4- Although the resistivity of these two kinds salts have similar variety behavior along with temperature, the pressure effect behaves obvious difference especially the high pressure. We assert that the difference relates to the π - d interaction. Here, we use the EDT - DSDTFVO to express ethylenedithiodiselenadithiafulvalenothioquinone - 1,3 - dithiolemethide.
