The pho­to­elec­tric ef­fect in stereo

In the photoelectric effect, a photon ejects an electron from a material. Researchers at ETH have now used attosecond laser pulses to measure the time evolution of this effect in molecules. From their results they can deduce ...

Researchers measure electron orbitals of molecules in 3-D

Many people will remember them from physics lessons at school: Often represented as colourful clouds or balloons, electron orbitals provide information on the whereabouts of the electrons in atoms and molecules. Scientists ...

Breakthrough unravels photoelectric effect

An international team including theorists from the Department of Electromagnetic Processes and Atomic Nuclei Interactions of the MSU Institute of Nuclear Physics managed, for the first time in the history of photoelectric ...

Graphene on its way to conquer Silicon Valley

The remarkable material graphene promises a wide range of applications in future electronics that could complement or replace traditional silicon technology. Researchers of the Electronic Properties of Materials Group at ...

New material promises better solar cells

Researchers at the Vienna University of Technology show that a recently discovered class of materials can be used to create a new kind of solar cell.

One in, two out: Simulating more efficient solar cells

(Phys.org)—Using an exotic form of silicon could substantially improve the efficiency of solar cells, according to computer simulations by researchers at the University of California, Davis, and in Hungary. The work was ...
