|Outline of Final Research Achievements
In this project, we developed optically detected magnetic imaging and its derivative imaging techniques. We explored multifaceted phenomena in nanostructures involving nuclear spins, charges and spins of electrons, holes, and excitons in GaAs, GaN, and dichalcogenides. Our imaging wavelength spanned from 350 nm in the ultraviolet to 800 nm in the near infrared regime. Using the unique imaging techniques developed in this project, we successfully studied many-body effects of skyrmions, real-space and real-time imaging of excited states of chiral edge channels of integer and fractional quantum Hall effects, and spin helix transport in GaAs systems. In GaN systems, we revealed the type and the spatial distribution of impurities. We also studied photoconductivity in graphene/InSe devices and showed new potential applications of Van der Waals crystals.
