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.   Research on mechanism of electrical transport of carbon aerogels (EI收录) 会议论文 Advanced Materials Research, Xi'an, China, January 15, 2011 - January 16, 2011 作者:  Feng, Yaning[1];  Yang, Rong[2];  Ge, Liling[1];  Jiang, Bailing[1];  Tanemura, Masaki[3] 收藏  |  浏览/下载：3/0  |  提交时间：2019/04/15 Electric conductivity  Field emission  Field emission microscopes  Materials  Porosity  Scanning electron microscopy  Transport properties
