CAMBRIDGE, Mass. -- A team of scientists at MIT have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. The discovery could lead to a new way of producing electricity, the researchers say.
Solar cells made from silicon are projected to be a prominent factor in future renewable green energy equations, but so far the promise has far exceeded the reality. While there are now silicon photovoltaics that can convert sunlight into electricity at impressive 20 percent efficiencies, the cost of this solar power is prohibitive for large-scale use.
Rice University researchers have found a way to stitch graphene and hexagonal boron nitride (h-BN) into a two-dimensional quilt that offers new paths of exploration for materials scientists.
The technique has implications for application of graphene materials in microelectronics that scale well below the limitations of silicon determined by Moore's Law.
DURHAM, N.H. -- A team of chemists from the University of New Hampshire has synthesized the first-ever stable derivative of nonacene, creating a compound that holds significant promise in the manufacture of flexible organic electronics such as large displays, solar cells and radio frequency identification tags.
MIT researchers have demonstrated the first laser built from germanium that can emit wavelengths of light useful for optical communications. It's also the first germanium laser to operate at room temperature. Unlike the materials typically used in lasers, germanium is easy to incorporate into existing processes for manufacturing silicon chips.
Quantum mechanics allows heat absorbed in submicron thin metal films over the full solar spectrum to be converted to electrical current by the photoelectric effect.
Novel research on improving the simulation performance of hardware models created in a language called SystemC, often used to shorten manufacturing design cycles to improve the time it takes to bring a product to the marketplace, has garnered a best paper award at the 15th Asia and South Pacific Design Automation Conference (ASP-DAC) for a team led by Sandeep Shukla, Virginia Tech associate pr
