quantum dots, room temperature self assembly

Brian Wang writes "University researchers are using self-assembly techniques and chip-related chemistry to develop a process for mass producing tiny crystals called quantum dots. Semiconductor nanocrystals promise a quantum leap over traditional optoelectronics due to their unique and size-tunable properties. Quantum dots measure a few nanometers in size and are already revolutionizing biological and environmental sensing due to their size-dependent luminescence. Other applications include telecommunications, photovoltaics, lasers and quantum computing. A research team at the University at Buffalo claims to have discovered a simple way to mass-produce quantum dots with extreme precision, in nearly any desirable size, using a technique based on self assembly and room-temperature chemistry.
