The experimental results are analyzed using theoretical models. The results reveal that the materials exhibit three conduction mechanisms: conduction in extended states  conduction in band tails  and conduction in localized states. Particularly  it is found that in a low-temperature regime  the conduction of the materials follows a band tail hopping mechanism  rather than the previously assumed variable range hopping mechanism. The results also reveal that energy gaps such as EC-E F and EC-EA decrease with increasing pyrolysis temperature. 2009 The American Ceramic Society.   电化学沉积和聚合物热解法制备类金刚石碳复合薄膜及其性能研究 学位论文  OAI收割 理学博士: 中国科学院研究生院, 2007 陈刚 收藏  |  浏览/下载：40/0  |  提交时间：2013/05/24 电化学沉积  聚合物热解  DLC复合薄膜  表面润湿性  场电子发射  Electrochemical deposition  Pyrolysis of polymer  DLC composite films  Wettability  Field electron emission
