(Phys.org)—Scientists have discovered that a solar cell consisting of two or three layers of quantum dots, with each layer tuned to a different part of the solar spectrum, has an efficiency that is 40-60% higher than the ...
(Phys.org)—While today's smart phones, tablets, and other small electronic devices rely on electrical data connections, in the future they may use optical connections in order to become even faster and smaller. Photonic ...
(PhysOrg.com) -- In an effort to make computer chips even faster than those of today, many researchers have recently been investigating the possibility of optical computing. In an optical computer, information is encoded ...
(PhysOrg.com) -- Semiconductors provide the bases for many different avenues of device research. Indeed, many of the technological devices that are commonplace in our society are reliant on semiconductors. However, as we ...
A team of researchers led by San Francisco State University's Weining Man is the first to build and demonstrate the ability of two-dimensional disordered photonic band gap material, designed to be a platform to control light ...
