Optical orientation of excitons in hybrid metal-semiconductor nanostructures
Abstract
We demonstrate the possibility of the optical orientation of excitons in the near field of the metal grating that covers a semiconductor nanostructure. Excitons generated this way have the wave vector greater than the wave vector of the incident radiation. We suggest that optical orientation method is applicable to study the fine structure and kinetics of the hot excitons in semiconductor quantum well.
