Recent experiments have revealed that electron transfer through chiral molecules is significantly influenced by the spin orientation of the electrons. This phenomenon, known as the chiral-induced spin selectivity (CISS) effect, poses theoretical challenges while also presenting opportunities for the advancement of organic and inorganic molecule-based spintronic devices. The CISS effect facilitates the preferential transfer of one type of spin over another through a chiral materials at room temperature. The interplay between spin direction and momentum in these materials effectively prevents electron backscattering, leading to the stabilization of a specific spin type during the transfer process, akin to an effective magnetic field. Essentially, the chirality of the molecular system functions as a spin filter at room temperature, eliminating the need for magnets to achieve spin injection. Nonetheless, several fundamental challenges must be addressed to realize the practical applications of the CISS effect. Key areas for improvement include controllability, durability, and the efficiency of spin polarization, all of which represent significant hurdles in the development of CISS-based molecular spintronic devices. While numerous compelling examples of the CISS effect have emerged in recent years, further experimental research is essential to fully explore its potential. Moreover, substantial efforts are needed to translate proof-of-concept results into tangible real-world applications. In light of this, it would be beneficial to consider designing a project on chiral materials in relation to the CISS effect, with the aim of generating spin-polarized currents and developing functional spin-based device applications.
