Replacing steel with lightweight Aluminum alloys could significantly improve fuel economy of vehicles. Existing lightweight alloys are difficult to use, because they have poor ductility, and tend to tear while they are stamped to form a complex part. Adding small quantities of additional allying elements to lightweight alloys could improve their ductility. But at present the only way to iden
Doping semiconductor nanocrystals with transition metals is an efficient route to tune emission color over a broad range of
Interacting electron ripples provide clues to superconductivity A theoretical prediction is confirmed by atomic-scale microscopy
Transition-metal oxides (TMO), such as molybdenum tri-oxide (MoO3), are promising hole-injection electrode materials for organic electronics because of their large work function and high conductivity. They are superior to the widely used organic polymer PEDOT:PSS which causes device degradation. However, deposition of MoO3 layers
Device characteristics under dark and illumination
Topological surface states are a new class of novel electronic states that are potentially useful for quantum computing or spintronicapplications. Unlike conventional two-dimensional electron states, these surface states are expected to be immune to localization and to overcome barriers caused by material imperfection.
Novel electronic applications often result from fresh theoretical insights into long-familiar materials. Recently, strong interest has focused on the “topological insulators”, notably Bi2Se3and Bi2Te3. In these solids, the electrons on the surface display highly unusual properties.
