| | ~~ | | 金属经过冷加工产生了缺陷,或者使晶体的电子结构有所变化,所有这些会影响金属的电阻率,本文在室温进行连续拉伸的过程中测量了铜、铝、铁、锌和镉五种金属的电阻率,并且观察拉伸速度对电阻率的影响。此外,还测量了在有应力与没有应力的情况下,电阻率的回复,发现锌的电阻率随延伸率的改变是先减少后增大,慢速拉伸铜时电阻率也是有变小的反常变化。最后,对这些反常电阻率的变化用能带概念作了初步的解释。 | | 文摘来源 | | In spite of the fact that many technical properties of recently developed humidity-sensitive semiconducting ceramics have considerably been improved, theoretical studies are rather inadequate, impeding further progress to be made in the idealization of the humidity-sensitive materials and devices.This paper analyzes theoretically the electronic process within the semiconducting ceramics under the influence of humidity according to the band structure, surface state and boundary state of the oxide semiconduct... | | 近几年发展起来的湿敏半导瓷,虽然在各种技术性能方面都有了较大的改进,但是在我国这方面的理论研究工作却仍做得很少,因而使湿敏材料及其器件的进一步发展受到了阻碍.本文从氧化物半导瓷的能带结构、表面态与界面态理论出发,分析了水份作用下在半导瓷中的电子过程,及电阻率温度系数的调整途径等问题.文中还着重对有关作用机理作了探讨. | | 文摘来源 | | It is shown in our experiments that the threshold current of the lasers decreases with the lowering of temperature, and finally enters saturation region. This is essentially consistent with Hwang's result in the range of 300-10 K. But further lowering in temperature will increase the threshold current of the lasers. We suppose that this iucreasement is caused by the leakage of carriers. When the temperature is in the range of 2.8-6 K, the threshold current, the voltage at the junction and the dynamic electr... | | 实验证明,温度下降,受激发射阈值电流下降,进入一个饱和区。这与Hwang在300—10K间的观察结果一致。但尔后又继续上升。我们认为这起因于载流子的泄漏。当温度在6—2.8K间阈值电流、结电压、动态电阻呈现规律性的结构。如果假设发生了电子-空穴凝聚,可用朗道相图作定性说明,但也可能起因于杂质能带。 | | 文摘来源 | |   | | << 更多相关文摘 |
