Mirror-Image Crystals Reverse the Direction of Light-Driven Currents

The circular photogalvanic effect (CPGE), a phenomenon that generates helicity-dependent photocurrents in noncentrosymmetric materials, can originate purely from a crystal's internal structure without a contribution from the surface, a study from Science Tokyo reveals.

Crystal Polarity Steers Light-Driven Currents in Hybrid Perovskites

Researchers at Institute of Science Tokyo showed that the bulk molecular arrangement of two-dimensional hybrid perovskite crystals dictates crystal polarity and reverses the direction of light-generated spin-polarized currents.

Reflective Crystals Specifically Reverse Light-Driven Photocurrent

Mirror-imaged crystals, opposite current: In two-dimensional hybrid perovskites, the direction of a photocurrent generated by circularly polarized light can be controlled via the inner polarity of the crystal. A new measurement geometry clearly separates the contribution of the crystal interior from disturbing surface effects and opens up paths to light-controlled spin construction elements. Tokyo (Japan). Electrons carry not only electric charg…
