New method controls the orientation of individual nanomaterials, which may soon lead to advances in LEDs, solar cells, smart windows and optical isolators.JIMING BAO AND FENG LIN, UNIVERSITY OF HOUSTON, AND JONATHAN HU, BAYLOR UNIVERSITYNanomaterials, such as nano-wires and nanotubes, are designed to have quantum confinement in one or two dimensions so that their properties in other dimensions can be engineered, differing from that of their corresponding bulk material. As such, the unique and superior properties of nanomaterials are always associated with their shape and symmetry. Consider graphene. A single layer of graphene absorbs about 2.3 percent of incident light, but this is only valid for incident light normal to the graphene plane; the absorption becomes zero when the electrical field of light is perpendicular...Read full articleRelated content from Photonics MediaARTICLESPhotoluminescence Techniques Map, Measure Semiconductor Thermal ConductivityAs new materials emerge, thermal conductivity measurements will need to be developed to handle materials with a small size and high thermal conductivity (k).
