Stacking two-dimensional materials may lower cost of semiconductor devices

Researchers have found that stacking materials that are only one atom thick can create semiconductor junctions that transfer charge efficiently, regardless of whether the crystalline structure of the materials is mismatched - lowering the manufacturing cost for a wide variety of semiconductor devices such as solar cells, lasers and LEDs.

Scalable growth of high quality bismuth nanowires

Bismuth nanowires have intriguing electronic and energy-harvesting application possibilities. However, fabricating these materials with high quality and in large quantities is challenging. Researchers have now demonstrated a new technique to produce single- crystal nanowires atop arbitrary substrates, including glass, silicon, and metal, when an intermediate layer of vanadium is present.

Researchers develop novel chiral nanostructures from helical polymers and metal salts

Scientists describe a novel protocol to obtain different types of nanostructures from a single helical polymer and certain metal salts. An outstanding characteristic of these macromolecules is that their helicity can be tuned by the action of diverse external stimuli such as temperature, polarity or metal ions. Consequently, these polymers act as sensors.
