Technology Update

Using a technique called optical two-beam super-resolution lithography, researchers in Australia have succeeded in making photonic “gyroid” nanostructures similar to those found in butterfly wings. The artificial structures, which outperform their natural counterpart in many ways, might be used in a variety of photonics and optics technologies…. http://nanotechweb.org/cws/article/tech/64982 Comparing an artificial and natural gyroid structure

t least five “hot carriers” are produced for every photon absorbed by superlattices made from graphene and boron nitride. This new result from researchers in New York, Tallahassee and Seattle, means that the carbon sheet could be used to make flexible optoelectronics devices such as ultrafast and highly efficient photodetectors and solar cells…. http://nanotechweb.org/cws/article/tech/64988 Moiré […]

Researchers in Australia and Singapore are the first to have measured the electronic properties of topological Dirac semimetal thin films, which are 3D analogues of graphene. These films, made from sodium bismuth, have high charge carrier mobilities and could be used to make new electronic devices like topological transistors…….. http://nanotechweb.org/cws/article/tech/64999 Na3Bi thin films
