We overview experiments performed on the chiral induced spin selectivity (CISS) effect using various materials and experimental configurations. Through this survey of different material systems that manifest the CISS effect, we identify several attributes that are common to all the systems. Among these are the ability to observe spin selectivity for two point contact configurations, when one of the electrodes is magnetic, and the correlation between the optical activity of the chiral systems and a material’s spin filtering properties. In addition, recent experiments show that spin selectivity does not require pure coherent charge transport and the electron spin polarization persists over hundreds of nanometers in an ordered medium. Finally, we point to several issues that still have to be explored regarding the CISS mechanism. Among them is the role of phonons and electron–electron interactions.

手性材料中的自旋选择性效应

我们概述了使用各种材料和实验配置对手性诱导自旋选择性（CISS）效应进行的实验。通过对表现出CISS效应的不同材料系统的调查，我们确定了所有系统共有的几个属性。其中之一是当电极之一为磁性时，观察两点接触配置的自旋选择性的能力，以及手性系统的光学活性与材料的自旋过滤特性之间的相关性。此外，最近的实验表明，自旋选择性不需要纯粹的相干电荷传输，并且电子自旋极化在有序介质中持续数百纳米。最后，我们指出了有关CISS机制仍需探索的几个问题。
