'Cleaning' boosts solar cell efficiency

Energy losses in nanowire solar cell can be significantly reduced by 'cleaning' the surface of the cells with a special etching method. This has been shown by researchers at Eindhoven University of Technology (TU/e), Delft ...

Cost-saving computer chips get smaller than ever

Not so long ago, a computer filled a whole room and radio receivers were as big as washing machines. In recent decades, electronic devices have shrunk considerably in size and this trend is expected to continue, leading to ...

A new light source for quantum computers

Researchers have discovered a new way of emitting photons one at a time. They have constructed semiconductor nanowires with "quantum dots" of unprecedented quality - a discovery with implications for the future of quantum ...

New '4-D' transistor is preview of future computers

(Phys.org)—A new type of transistor shaped like a Christmas tree has arrived just in time for the holidays, but the prototype won't be nestled under the tree along with the other gifts.

Semiconductors with electric and magnetic properties

European scientists developed solid-state semiconductor components with magnetic properties, a prerequisite for a new generation of electronic devices exploiting both the charge and the spin of electrons.

Towards replacing silicon with graphene

Norwegian researchers are the world's first to develop a method for producing semiconductors from graphene. This finding may revolutionize the technology industry.
