New graphene sensor to improve hepatitis diagnosis

Mon, 22 May 2017 08:30:02 EDT

A new UK-China collaborative project is developing a sensor to provide an easy, low-cost method of diagnosing hepatitis on the spot using graphene – an advanced 2-D material known for its high electrical conductivity.

Let there be light: Controlled creation of quantum emitter arrays

Mon, 22 May 2017 05:00:03 EDT

Transition metal dichalcogenides (TMDs) are layered semiconductors that can be exfoliated into layers only a few atoms thick. Recent research has shown that some TMDs can contain quantum light sources that can emit single photons of light. Until now, the occurrence of these quantum light emitters has been random. Now, researchers in the Graphene Flagship working at the University of Cambridge, UK, have created large scale arrays of these quantum emitters in different TMD materials. The work, also involving researchers from Harvard University, US, is published in Nature Communications. This new approach leads to large quantities of on-demand, single photon emitters, paving the way for integrating ultra-thin, single photons in electronic devices.

The team of researchers headed by Prof. Dr. Sabine Maier, Prof. Dr. Milan Kivala and Prof. Dr. Andreas Görling has successfully assembled and tested conductors and networks made up of individual, newly developed building block molecules. These could in future serve as the basis of components for optoelectronic systems, such as flexible flat screens or sensors. The FAU researchers have published their results in the journal Nature Communications.

Gold nanoparticle chains show promise as light conductors

Thu, 18 May 2017 09:24:38 EDT

Today's computers are faster and smaller than ever before. The latest generation of transistors will have structural features with dimensions of only 10 nanometers. If computers are to become even faster and at the same time more energy efficient at these minuscule scales, they will probably need to process information using light particles instead of electrons. This is referred to as "optical computing".

Managing stress helps transistor performance

Tue, 16 May 2017 11:30:48 EDT

Tensile mechanical stress can have a useful effect for some transistors, where the resulting atomic strain allows its current-carrying electron-hole pairs better mobility. However, when that stress is applied to the whole device, as is a popular approach via use of what's called contact etching stop layers (CESLs), the drift region adjacent to the stretched channel is compressed and results in reduced performance.
