Inducing Chirality in Single Photon Quantum Emitter Photoluminescence via the Chiral Induced Spin Selectivity Effect

ORAL

Abstract

Abstract:

Chiral quantum emitters or non-reciprocal single photon devices would play a significant role in future quantum communication-based infrastructure. [1,2] To date, the realization of such quantum emitters has been difficult as they generally require complex and bulky experimental infrastructures such as high magnetic/electric fields and cryogenic-temperatures. The Chiral-Induced Spin Selectivity (CISS) effect is one well-known physical phenomena known to enable control over electronic spins via the asymmetric transport of electronic spins in chiral organic and inorganic systems. [3,4] Our group has explored the utilization of CISS to manipulate the chirality of photoluminescence (PL) of single quantum emitters. Cadmium selenide-quantum dots are immobilized on a chiral surface prepared using electrodeposition of aniline. We observe both the inducement a significant degree of circular polarized PL emission and a magnetization-dependent PL quenching by using a ferromagnet valve in the chiral substrate. These observations illustrate the potential of a CISS-based mechanisms for realizing chiral single photon emission sources in solid-state material devices.
