Materials Characterization

Structure-property relations are a key component of materials science. Characterization techniques are used to probe a materials structure, either optically, electronically, magnetically, or through mechanical means. The elemental makeup of materials can be determined through a large number of techniques, including x-ray fluorescence, mass spectroscopy, and X-ray diffraction.

Nanowires & Devices

Nanowires are near one- dimensional structures that typically have a length-to-width ratio of a thousand or more. Because of their small diameters (on the order of a few nanometers), nanowires can exhibit unusual quantum effects that differ from the properties of the same materials in bulk. Nanowires are made from a number of materials, including silicon, metals, dielectrics and a variety of composite materials. Nanowires are commonly grown by a vapor-liquid-solid mechanism using chemical vapor deposition and by molecular beam epitaxy techniques.
