Abstract

The control of complex devices on the nanoscale is challenging. The development of nanoparticles, such as quantum dots, that serve as "artificial atoms" enables the manipulation of energy levels at the nanoscale. Using quantum dots and wet chemistry, multilayer structures with unique coupling properties can be realized. The coupling of such quantum dots is essential for several applications, such as parallel computing. Earlier work showed enhancement of the delocalization using covalent bonds and short linkers. Here, we demonstrate a way to achieve better coupling using helical chiral molecules that exhibit long spin-wave function delocalization. The delocalization is controlled by manipulation of the spin state using polarized light.
