关键词	The electron transport behavior of polymer-derived amorphous silicon oxycarbonitride ceramics is studied by measuring their temperature-dependent electrical conductivities. 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.
