Pressure effect study on the I-V property of the GaAs-based resonant tunnelling structure by photoluminescence measurement 下载免费PDF全文
This paper discusses the I-V property of the GaAs-based resonant tunnelling structure (RTS) under external uniaxial pressure by photoluminescence studies. Compressive pressure parallel to the [110] direction, whose value is determined by Hooke's law, is imposed on the sample by a helix micrometer. With the increase of the applied external uniaxial compressive pressure, the blue shift and splitting of the luminescence peaks were observed, which have some influence on the I-V curve of RTS from the point of view of the energy gap, and the splitting became more apparent with applied pressure. Full width at half maximum broadening could also be observed. 相似文献

本文通过分析洗衣机的洗衣过程,认为是一次性溶解、多次稀释的过程。据此建立动态规划模型,并利用迭代公式和最优化原理,得出最少用水量的判断公式和代数解,以海棠洗衣机为例,通过对比,利用我们的模型算出的用水量比厂家提供的数据要小,从而说明所建模型的优越性。最后,根据模型解,给出最小用水量与赃衣服的重量的关系图,并从中得出有趣的结论,也给厂家提供一个节约用水的程序。 相似文献
