'Magic' alloy could spur next generation of solar cells

In what could be a major step forward for a new generation of solar cells called "concentrator photovoltaics," University of Michigan researchers have developed a new semiconductor alloy that can capture the near-infrared ...

Silicon-carbide modulator overcomes decades long 'missing block'

A collaboration with Harvard University has led to the development of a new-generation electro-optic modulator that could stamp out its bulky predecessor through the creation of a smaller, stronger, cooler, faster and cost-effective ...

Photonic crystal and nanowire combo advances 'photonic integration'

Contrary to the tremendous success story of electronic integration, photonic integration is still in its infancy. One the most serious obstacles it faces is the need to use a variety of materials to achieve different functions—unlike ...

Heart of an exploded star observed in 3-D

Supernovas—the violent endings of the brief yet brilliant lives of massive stars—are among the most cataclysmic events in the cosmos. Though supernovas mark the death of stars, they also trigger the birth of new elements ...

Silicon solves problems for next-generation battery technology

Silicon – the second most abundant element in the earth's crust – shows great promise in Li-ion batteries, according to new research from the University of Eastern Finland. By replacing graphite anodes with silicon, it ...
