Scientists demonstrate high-efficiency quantum dot solar cells

Research shows newly developed solar powered cells may soon outperform conventional photovoltaic technology. Scientists from the National Renewable Energy Laboratory (NREL) have demonstrated the first solar cell with external ...

Photonic quantum computers: A brighter future than ever

(Phys.org) —Harnessing the unique features of the quantum world promises a dramatic speed-up in information processing as compared to the fastest classical machines. Scientists from the Group of Philip Walther from the ...

Physicists create world's smallest semiconductor laser

Physicists at The University of Texas at Austin, in collaboration with colleagues in Taiwan and China, have developed the world's smallest semiconductor laser, a breakthrough for emerging photonic technology with applications ...

Ultra-short laser pulses control chemical processes

Specially shaped laser pulses can be used to change the state of electrons in a molecule. This process only takes several attoseconds—but it can initiate another, much slower process: The splitting of the molecule into ...
