PrBa2Cu3O7－δ膜的电阻率和热电势
RESISTIVITY AND THERMOELECTRIC POWER OF PrBa2Cu3O7-δ FILM
【摘要】 在７７Ｋ到３００Ｋ的温度范围内测量了ＰｒＢａ２Ｃｕ３Ｏ７－δ薄膜的电阻率和热电势．通过用变程跳跃（ＶＲＨ）和近邻跳跃（ＮＮＨ）模型的公式拟合实验数据，发现这种材料的电阻率和热电势行为可以用跳跃机制解释．
【Abstract】 AbstractThe resistivity and thermopower of a PrBa2Cu3O7-δ film is measured from 77K to 300K. By fitting the data with variable-range- hopping and nearest-neighbor- hopping formula, it is shown that the behavior of resistivity and themopower can be well understood in terms of the hOPPing mechanism.
