Research may Pave the Way for Development of More Efficient Optoelectronic Devices

Diodes are widely used electronic devices that act as one-way switches for current. A well-known example is the LED (light-emitting diode), but there is a special class of diodes designed to make use of the phenomenon known as "quantum tunneling".

Researchers Synthesize Organic Light-Harvesting Supramolecule Based on DNA

Organic molecules that capture photons and convert these into electricity have important applications for producing green energy. Light-harvesting complexes need two semiconductors, an electron donor and an acceptor. How well they work is measured by their quantum efficiency, the rate by which photons are converted into electron-hole pairs.
