Since the initial landmark study on chiral induced spin selectivity (CISS) effect in 1999, considerable experimental and theoretical efforts have been made to understand physical underpinnings mechanistic features of this interesting phenomenon. As first formulated, CISS refers innate ability materials act as filters for electron transport; however, more recent experiments demonstrate that displacement currents arising from charge polarization molecules lead without need net flow. With its identification a fundamental connection between symmetry materials, promises profound ubiquitous implications existing technologies new approaches answering age old questions, such homochiral nature life. This review begins with discussion different methods measuring then provides comprehensive overview known exhibit CISS-based phenomena before proceeding identify structure-property relations delineate leading models effect.

Ultrawide bandgap semiconductor β-Ga2O3 (4.9 eV), with its monoclinic crystal structure, exhibits distinct anisotropic characteristics both optically and electrically, making it an ideal material for solar-blind polarization photodetectors. In this work, epitaxial films were deposited on sapphire substrates different orientations, the mechanisms underlying anisotropy of these investigated. Compared to c-plane sapphire, lattice mismatch between m- or r-plane is more pronounced, disrupting rotational symmetry rendering them anisotropic. Thanks improved anisotropy, ratio photodetector based grown 0.24, nearly ten times higher than that substrates. Finally, by utilizing polarization-sensitive photodetectors, we developed encrypted ultraviolet optical communication system. Our work provides a new approach facilitate fabrication application high-performance
