金属半导体锰氧化物

The Manganites as Metallic Semiconductors

Boris V. Karpenko, Alexander V. Kuznetzov

摘要:

提出了具有金属和半导体性质的双带模型。该模型可以解释在理论参数之间的适当关系下电阻温度极大值的出现。计算在紧束缚近似下进行。讨论了该模型对锰氧化物的适用性。

英文摘要:

The two-band model possessing metal and semiconductor properties is offered. This model may explain the appearance of temperature maximum of the electrical resistance at the proper relationships between the parameters of the theory. The calculations are carried in the tight-binding approximation. The applicability of the model to the manganites is discussed.
