Light and quantum devices emerge

摘要

As LEDs and lasers become increasingly nimble, powerful and better controlled, it needs no crystal ball to predict that emerging products, often targeting niche markets, will need compound devices. Quantum computing is not vying for top place currently, but others in the quantum brigade are. Expect a flood of products using quantum well layers, cascade structures, dots, rods, wires, infrared detectors, interference devices, and tunnelling composites. And note that electronic, magnetic and optoelectronic applications for nanoparticles will account for 74.2% of a 2005 world market that is expected to exceed $900m.
