A research team in Kiel has demonstrated a previously unknown effect in graphene—a single layer of carbon atoms whose discovery earned the 2010 Nobel Prize. For years, graphene has been seen as a ...

Scientists observed record-breaking electron mobility — seven times higher than in conventional semiconductors — with a material made from the same elements as quartz and gold. When you purchase ...

An elusive behavior of electrons has finally been isolated from more mundane electron activity in a real-world material. A team of physicists led by Ryuhei Oka of Ehime University has measured what ...

This revealed two distinct types of SEEs with different origins. One group is connected to solar flares exploding from small ...

The Nobel Physics Prize this year went to physicists Anne L’Huillier, Pierre Agostini, and Ferenc Krausz for developing a way to spy on the ultra-fast lives of electrons. The physicists’ combined 40 ...

I first learned of this area of research as a graduate student in physical chemistry. My doctoral adviser’s group had a project dedicated to studying chemical reactions with attosecond pulses. Before ...

Oak Ridge National Laboratory and North Carolina State University researchers have developed a simulation capable of predicting how tens of thousands of electrons move in materials in real time, or ...

Scientists have developed a simulation that can predict how tens of thousands of electrons move in materials in real time, or natural time rather than compute time. Developed by a team from the ...

The interactions in photovoltaic materials that convert light into electricity happens in femtoseconds. How fast is that? One femtosecond is a quadrillionth of a second­­. To put that in perspective, ...

BUFFALO, N.Y. — Scientists have used electrical pulses to manipulate magnetic information into a polarized light signal, a discovery that could revolutionize long-distance optical telecommunications, ...
