All-inorganic nanocrystals boost infrared emission

New chemistry has been developed to integrate lead chalcogenide nanocrystals into continuous inorganic matrices of chalcogenide glasses. Inorganic capping, rather than conventional organic capping ligands, allows simple and ...

SNS, HFIR experiments help refine thin-film solar cells

(PhysOrg.com) -- Solar cells that convert sunlight into electricity could be a widely used renewable energy source. Getting to that point, though, requires breakthroughs in their cost and their efficiency at turning sunbeams ...

Expanding the degrees of surface freezing

(PhysOrg.com) -- As part of the quest to form perfectly smooth single-molecule layers of materials for advanced energy, electronic, and medical devices, researchers at the U.S. Department of Energy's Brookhaven National Laboratory ...

Single-crystal films could advance solar cells (w/ Video)

(PhysOrg.com) -- Cornell researchers have developed a new method to create a patterned single-crystal thin film of semiconductor material that could lead to more efficient photovoltaic cells and batteries.

How 'random' lasers work

When University of Utah scientists discovered a new kind of laser that was generated by an electrically conducting plastic or polymer, no one could explain how it worked and some doubted it was real. Now, a decade later, ...
