【摘要】 针对TiS₂电输运性质中散射机制的争论,我们测量了化学计量TiS₂的单晶、多晶粉末,和非化学计量的多晶粉末的热电势率S（T）（温度T在90-400K之间）. 将载流子-载流子散射和Fivaz同极光学声子散射这两种模型的计算结果分别与S（T）的实验值进行了比较,认为能同时对S（T）和ρ（T）给出比较满意的解释的是Fivaz同极光学声子散射说.更多还原

【Abstract】 A correlation curve for thermoelectric power S vs.temperature T within the range90-400 K has been measured in accordance with the problem concerning the scatteringmechanism of electric transport process in TiS₂.A comparison of the measured datawith the theoretical curves is given based on the homopolar optical phonon scatteringand the carrier-carrier scattering hypotheses.It is believed that the homopolar opticalphonon scattering mechanism would be more acceptable.更多还原
