Revolutionary solar-friendly form of silicon shines

Silicon is the second most-abundant element in the earth's crust. When purified, it takes on a diamond structure, which is essential to modern electronic devices—carbon is to biology as silicon is to technology. A team ...

Harnessing an unusual 'valley' quantum property of electrons

Yoshihiro Iwasa and colleagues from the RIKEN Center for Emergent Matter Science, the University of Tokyo and Hiroshima University have discovered that ultrathin films of a semiconducting material have properties that form ...

Organic tin in polymers increases their light absorption

Researchers of the Christian-Albrechts-University of Kiel (CAU), Germany, successfully integrated organic tin into semiconducting polymers (plastics) for the first time. Semiconducting polymers can be used, for example, for ...

Solar cell compound probed under pressure

Gallium arsenide, GaAs, a semiconductor composed of gallium and arsenic is well known to have physical properties that promise practical applications. In the form of nanowires and nanoparticles, it has particular potential ...

Photo-initiated charge separation in nanobiohybrid complex

In natural systems, electron flow is mediated by proteins that spatially organize donor and acceptor molecules with great precision. Achieving this guided, directional flow of information is a desirable feature in photovoltaic ...

New physical phenomenon on nanowires seen for the first time

Very tiny wires made of semiconducting materials – more than one thousand times thinner than a human hair – promise to be an essential component for the semiconductor industry. Thanks to these tiny nanostructures, scientists ...

Scientists probe the next generation of 2-D materials

As the properties and applications of graphene continue to be explored in laboratories all over the world, a growing number of researchers are looking beyond the one-atom-thick layer of carbon for alternative materials that ...
