针对TiS_2电输运性质中散射机制的争论,我们测量了化学计量TiS_2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.
In response to the controversy over the scattering mechanism of the electrical transport properties of TiS_2, we measured the thermoelectric power S (T) of single-crystal, polycrystalline, and non-stoichiometric polycrystalline powders of stoichiometric TiS_2 (temperature T at 90-400 K The results of carrier-carrier scattering and Fivaz homopolar phonon scattering are respectively compared with the experimental values of S (T), and it is considered that S (T) and ρ (T) gives a more satisfactory explanation of Fivaz homopolar phonon scattering said.
