  The spin Hall effect(SHE)and inverse spin Hall effect(ISHE)have become increasingly important because of their intriguing physics and great applications in the charge-spin conversion.It is commonly known that the SHE arises from the spin orbit coupling(SOC)[1].As an outstanding issue,however,the qualitative dependence of the SHE on the SOC strength is still unclear.In order to enhance the charge-spin conversion efficiency and to reveal the mechanism of the SHE,it is imperative to study the SHE in nonmagnetic alloys in which the SOC strength can be tuned continuously in a wide range.

小斜率算法是一种比较实用的粗糙面电磁散射计算方法,但是其需要处理的数据量比较大,计算比较耗时。在处理大粗糙面电磁散射问题时,会消耗大量内存,经常出现内存溢出问题,导致无法计算。为解决内存不足够的问题,采用硬盘存储数据的方法是一个可行方案。但这种方法的缺点是硬盘读写数据速度低,会降低计算效率。虽然可以采用辅助线程,减小硬盘与内存之间数据传输过程对计算效率的影响,但是效果有限。

台阶自由能是界面形核与晶体生长的关键参数,但是关于固-液界面中台阶自由能的直接测量研究几乎为空白。由于固-液界面处在材料内部,实验上直接观测固-液界面性质十分困难。原子模拟技术经过20多年的发展已经成为研究固-液界面性质的主要手段。

将5种不同折射率的液晶分别填入实芯光子晶体光纤的空气孔中,通过改变外场条件,研究其输出光谱的变化规律,并进行了理论模拟分析。结果表明:填充液晶后,输出光谱由全通变为多个波峰的带隙式;同时,液晶的折射率差值越大, 其波峰位置越向长波长方向移动,且相对光强的对比度可以达到16 dB;温度由20℃上升到85 ℃时,波峰向短波长方向移动,最大调控范围可达41 nm;调节电压从0—250 V,输出光谱的相对
