Researchers have developed a contactless method to study how mirror-image materials respond differently to circularly polarized light. The new approach eliminates the need to build complete electronic devices to test the materials.

The technique is based on light-induced charge separation, which allows researchers to directly probe how the material's structure acts like a microscopic filter. The method examines how the structure influences how electrons separate and move within the material.
