摘要
通过研究发现在某一特定温度附近时,TiO_2半导体特性明显发生改变,由非简并性半导体转化成为简并性半导体。采用自旋相关效应和库仑效应的理论,解释了能带模型失效的问题。
In this paper, it reveals that the semiconductor characteristics of titanium oxide change dramatically around a specific temperature; the titanium oxide changed to nondegenerate semiconductor from a degenerate one. On applying the self spin correlation effect and coulomb theory, this article give a explanation to the problem of the disability of energy band mode.
