hopping conductivity 中文意思是什麼

hopping conductivity 解釋
跳動傳導
  • hopping : adj. 1. 忙碌的,繁忙的。2. 從一處到另一處的;到處奔忙的。
  • conductivity : n. 【物理學】傳導性[力],傳導率;導電率[性,系數]。
  1. The temperature dependences on the resistance in all the thin films show that in the low temperature range the width of eg band level changes the transports, but in the high temperature range the thin films forms the small polarons hopping conductivity. the phase transition induced by the current is explained by the demagnetization and lattice distortion

    在高溫部分,材料呈現小極化子跳躍形式輸運特徵;實驗研究了不同偏置電流對薄膜的相變影響,表明電場可以引起材料中磁性的變化和晶格畸變,導致相變溫度點向低溫方向移動;材料的光致相變研究表明光子能量、光強和極化方向對輸運性質有影響。
  2. The magnitude of the conductivity maximum increases and shifts to lower temperature with increasing sr content. in this paper, the electrical conductivity reaches maximum value at x = 0. 4. below the temperature corresponding to the maximum value, the electrical conductivity is found to follow the relationship for the small polaron hopping mechanism, charge compensation of oxygen vacancy dominates electrical conduction at high temperature, and oxygen vacancy acts as traps to catch carriers, resulting in the decrease of carriers concentration and mobility

    通過電學和熱學性能測試結果表明,電導率隨著sr含量的增加以及溫度的變化都出現了極大值,在本論文中,在sr含量為0 . 4時電導率值最大,電導率最大值對應的溫度隨著sr含量的增加而降低,這是由於在低溫下以小極化子導電機理為主,在高溫階段則是氧空位的電荷補償占據主導作用,氧空位使得載流子的濃度和可動性減弱,從而導致電導率降低。
