Semiconductor Nanowires: from Nanolasers to Photochemical diodes

For centuries, wires played crucial roles: power lines for electricity, optical fibers for data, and cables for bridges. In the past 30 years, nanowires, 1000 times thinner than hair, transformed computing, photonics, energy, and biomedicine. Controlled semiconducting nanowires enable lasers, solar cells, transistors, probes, thermoelectrics, and (bio)photochemical diodes. Essential for photovoltaics and solar-to-fuel conversion, nanowires oer high surface area and tunable bandgap. This talk explores their history, synthesis, photonics, thermoelectrics, and artificial photosynthesis.
