| Abstract Scope |
Chiral semiconductors, exhibiting both circular dichroism and chirality induced spin selectivity (CISS), could greatly advance the fields of quantum computing and spintronics. However, creating entirely enantiospecific inorganic chiral materials is challenging. It is therefore necessary to create hybrid materials that optimize the chiroptical properties of a chiral organic and the semiconducting ability of an inorganic. Here, we demonstrate two methods of introducing small chiral amines into inorganic systems to create twisted, chiral nanostructures of lead halide perovskite and zinc oxide. The first portion involved creating a new growth of chiral 2D layered perovskite with R/S-MBA<sup>+</sup> forming a bilayer between perovskite Pb-I monolayers (n=1), resulting in microplates of R/S-(MBA)<sub>2</sub>Pb<sub>4</sub>. The second portion introduced (S)-(+)-2-amino-1-propanol to the 1D growth of ZnO, resulting in twisted ZnO nanowires. Further characterization of these materials will reveal exactly how they can be used in various electronic applications. |
