Strain affects the band structure of semiconductor materials, allowing the alteration of properties dictated by nature. Over the last 15 years, advances in epitaxy and, in particular, the epitaxy of ...

Thermal oxide is 'grown' on the surface of silicon wafers by diffusing oxygen atoms into the silicon's crystal lattice. The oxygen atoms break silicon-silicon bonds and form silicon-oxygen bonds ...

Frame (a) shows a schematic of the Nanonet, a lattice structure of Titanium disilicide (TiSi2), coated with silicon (Si) particles to form the active component for Lithium-ion storage. (b) A ...

“If you strain the silicon lattice, then you can improve the electron mobility and performance in your device,” says John Rogers, professor of material science at the University of ...

Moreover, silicon wafers are available in larger quantities, at lower cost, with better quality than any of the plausible alternative materials. Still, the need for compatibility with silicon wafers ...

Mesoporous silicon is crystalline silicon with disordered nanometer-sized pores. The material has a huge internal surface area and is also biocompatible.

When photons hit the surface of a solar cell, ... This material is made by using precision lasers to "zap" sulfur atoms into the silicon lattice in well-defined patterns.

Solar cells made from black silicon Date: October 9, 2012 Source: Fraunhofer-Gesellschaft Summary: Solar cells convert three-quarters of the energy contained in the Sun's spectrum into electricity ...

Solar cells convert three-quarters of the energy contained in the Sun's spectrum into electricity -- yet the infrared spectrum is entirely lost in standard solar cells. In contrast, black silicon ...
