Superconducting quantum-dot turnstile singles out electrons

A metallic quantum dot sandwiched between two superconductors – which functions as an electronic turnstile, only permitting one electron through at a time – has been developed by researchers in France, Russia and Finland. By driving an AC voltage through the device, the researchers can control the tunnelling of electrons into and out of the dot. While such turnstiles have been made before, this is the first where electrons at only one quantum energy level are allowed to pass through. This, say the researchers, makes the device ideal for quantum-metrology applications......

Photoactive pixels switch on and off

Thanks to photocurrent spectral atomic force microscopy (PCS-AFM), researchers at the Massachusetts Institute of Technology (MIT) say they have been able to observe photoactive pixels switching on and off in a heterostructure made of two different 2D materials. The technique might help in the design of new electronic and optoelectronic devices based on these atomically thin structures......

Photonic gyroids mimic butterfly wings

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....

Collecting hot carriers in graphene superlattices

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....
