Into another dimension: Nanoscale trilayer exhibits ultrafast charge transfer in semiconductor materials

Advancements in optoelectronic semiconductor technology are heavily reliant on the controlled movement of charges and excitons—pairs of electrons and holes—towards specific directions to generate fuel or electricity. Mirroring the mechanism of photosynthesis, where pigments capture solar energy and funnel it to a reaction center for conversion and utilization, photons in this process create electron-hole pairs.
