Early stage work shows graphene could be used as a semiconductor

A team of researchers from three US universities has demonstrated a way to vary the number of electrons in a give region of a piece of graphene. The team says this is a proof of principle in the creation of semiconductor devices using the so called 'wonder material'. It adds that the number of electrons can be tuned through the application of an electric field and says this could enable future devices to be 'rewired' dynamically.

240MHz RX71M MCUs shipping says Renesas

Renesas Electronics says the RX71M group – the flagship product in the RX Family of 32bit microcontrollers – is now shipping. Developed for use in industrial equipment, the devices run at up to 240MHz and come with up to 4Mbyte of on chip flash.

Kevlar barrier could prevent Li-ion battery fires

A Kevlar based barrier between the electrodes in a lithium-ion battery has been developed by the University of Michigan. The development is believed to prevent fires of the kind believed to have grounded Boeing's 787 Dreamliner in 2013.

Micro ring could hasten the adoption of quantum cryptography

Engineers from Università degli Studi di Pavia have created a micro-ring that entangles individual particles of light. The design is based on a micro ring resonator, a loop etched onto a silicon wafer that can capture and emit particles of light. By tailoring the resonator's design, the researchers created a small and highly efficient source of entangled photons.

USB 3.0 scope range offers 200MHz bandwidth

A range of oscilloscopes from Pico Technology is said to be suited to use by mainstream electronics design engineers. Called the PicoScope 3000D Series, the devices offer bandwidths of up to 200 MHz, two or four analogue channels plus 16 digital channels on the mixed signal models. With memory sizes ranging from 64 to 512Msamples, the scopes offer a maximum real time sampling rate of 1Gsample/s and feature a USB 3.0 interface and a built-in arbitrary waveform generator.

Design and engineering centre opened

Nick Gibb, secretary of state for education, has officially opened a new design and engineering centre at John Warner School, an 11 to 18 comprehensive school in Hoddesdon. The new block will support students at the school in a range of topics, including electronics, robotics and design.

Stable long term operation of graphene devices achieved

Although graphene based devices have shown outstanding electrical and optical performance, they are sensitive to environmental factors, such as humidity or gas composition. This, says a research team, has made reproducible operation in a normal atmosphere impossible.

Top 10 buy 37% of all semiconductors

The top 10 consumer electronics companies bought $125.6billion worth of semiconductors in 2014, equivalent to 37% of all semiconductor purchases and 9.4% more than in 2013, according to a report from market analyst Gartner. Together, Samsung Electronics and Apple bought $57.9bn of semiconductors in 2014, $3.9bn more than in 2013 and equivalent to 17% of total semiconductor demand. However, whilst the top 10 spenders grew their consumption by 9.4%, Apple and Samsung's combined spend grew by 7.1%.

Scientists say graphene allows control of light emission

Lasers, displays and other light emitting depend upon the electrically controlled modulation of photons. But, says a research team, electrical control of the light emission pathways opens up the possibility of novel types of nano photonics devices, based on active plasmonics.

York EMC opens Grangemouth facility

York EMC Services has opened a new compliance test laboratory, relocating its Scottish operation from Dalgety Bay to Grangemouth. The purpose built laboratory offers a range of EMC, safety, radio, telecoms and EMF compliance services to companies in Scotland and the North of England.

Metamaterial optical performance enhanced by nanocrystals

The emission of light from and capture of light by metamaterials can be enhanced with the use of light emitting nanocrystals, according to research conducted by the City College of New York, along with scientists from the University of Alberta and Purdue University. The work is believed to have application in ultrafast LEDs, nanoscale lasers and single photon sources.

Researchers use a nib to change optical properties of polymer semiconductors

Scientists at Imperial College London have developed a way to manipulate the optical properties of polymers by drawing patterns with a solvent 'ink'. The approach is said to allow more precise control over how these materials interact with light and could have application in all kinds of devices that emit, detect and control light. One example offered by the research team is the ability to make tiny LEDs that emit light in one direction only, rather than across a broad range of angles, thereby offering the prospect of compact light source arrays for medical diagnostic applications.
