Moving Silicon Atoms in Graphene

Moving Silicon Atoms in Graphene

Richard Feynman famously posed the question in 1959: is it possible to see and manipulate individual atoms in materials? For a time his vision seemed more science fiction than science, but starting with groundbreaking experiments in the late 1980s and more recent developments in electron microscopy instrumentation it has become scientific reality. However, damage caused [...]

A Transistor-Like Amplifier for Single Photons

A Transistor-Like Amplifier for Single Photons

Data transmission over long distances usually utilizes optical techniques via glass fibres — this ensures high speed transmission combined with low power dissipation of the signal. For quite some years possibilities have been explored how to go one step further and perform all-optical data processing, with optical transistors and optical logic gates. In particular in [...]

Move Over, Silicon: A New Circuit in Town

Move Over, Silicon: A New Circuit in Town

When it comes to electronics, silicon will now have to share the spotlight. In a paper recently published in Nature Communications, researchers from the USC Viterbi School of Engineering describe how they have overcome a major issue in carbon nanotube technology by developing a flexible, energy-efficient hybrid circuit combining carbon nanotube thin film transistors with [...]

Charging Portable Electronics in 10 Minutes

Charging Portable Electronics in 10 Minutes

Researchers at the University of California, Riverside Bourns College of Engineering have developed a three-dimensional, silicon-decorated, cone-shaped carbon-nanotube cluster architecture for lithium ion battery anodes that could enable charging of portable electronics in 10 minutes, instead of hours.   Lithium ion batteries are the rechargeable battery of choice for portable electronic devices and electric vehicles. [...]

Playing Pool With Carbon Atoms

Playing Pool With Carbon Atoms

A University of Arizona-led team of physicists has discovered how to change the crystal structure of graphene, more commonly known as pencil ‘lead’, with an electric field, an important step toward the possible use of graphene in microprocessors that would be smaller and faster than current, silicon-based technology.   Graphene consists of extremely thin sheets [...]

Tiny Flexible Cell Phones to Print On Clothes?

Tiny Flexible Cell Phones to Print On Clothes?

A new version of “spaser” technology being investigated could mean that mobile phones become so small, efficient, and flexible they could be printed on clothing.   A team of researchers from Monash University’s Department of Electrical and Computer Systems Engineering (ECSE) has modelled the world’s first spaser (surface plasmon amplification by stimulated emission of radiation) [...]
