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 […]

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

A new ultrathin and ultraflexible coating that can be made into an organic light-emitting diode (OLED) display for use as electronic skin, or e-skin, has been developed by researchers at the University of Tokyo. Once applied to the skin, the coating can measure blood oxygen levels and heart rates……… http://nanotechweb.org/cws/article/tech/64708 Ultra-thin electronic skin

A new way to control light using liquid crystals has been developed by researchers in Japan, who believe that their method offers many of the advantages of an artificial “metasurface” while being much easier to fabricate on an industrial scale. Among other applications, the researchers believe the work could be useful for the production of […]

A new technique to make thin films from suspensions of ball-milled coal has been developed by researchers at the Massachusetts Institute of Technology (MIT). The films, which retain the rich carbon chemistry of the starting coals, could be used to fabricate a range of nanoelectronics devices, including transistors, photovoltaics and battery anodes…. http://nanotechweb.org/cws/article/tech/64744 Making organic […]

A single carbon nanotube has been used as a scalable and tunable light source and integrated into a nanoscale waveguide by researchers in Germany. The nanotubes are part of a photonic-crystal waveguide that converts electric signals into light. The researchers hope their work could advance the field of optoelectronics and help to produce faster computer […]

Researchers at the University of Toronto and University Health Network in Canada have performed the first full clinical study showing that quantum-dot barcodes can be used to diagnose patients infected with the hepatitis B virus. The new work is a “critical step” to translating quantum-dot technology into medical applications, they say…. http://nanotechweb.org/cws/article/tech/64760 In the lab

Nanolayers Research Computing aims to bridge the gap between academic physics and real world products. The company was founded in 2015 to provide consultancy in modelling and simulations rather than “black box” software development, and business opportunities are already piling in…….. http://nanotechweb.org/cws/article/tech/64525 Work on “CritCat” in June 2016

Researchers at the universities of Oxford and Warwick in the UK have used a DNA nanomachine to control a set of chemical reactions in a sort of nanoscale manufacturing line that they have dubbed a molecular assembler. The reactions in question normally occur very slowly, but the DNA molecules help to bring the reactants closer […]

A high-quality, flexible transistor, made entirely from colloidal nanocrystals, has been developed by a team in the US. By sequentially depositing their components in the form of nanocrystal “inks,” the researchers could make transistors using standard industrial methods, without the need for high-temperature, high-vacuum specialist equipment. The work can be scaled up, so it could […]

Physicists in the US are the first to use a combination of light and sound to control the state of a diamond-based quantum bit (qubit) of information. The team used a laser pulse and a sound wave to modify the energy state of an electron in a nitrogen vacancy (NV) centre in diamond. According to […]
