Random nanowire configurations boost conductivity
Bethlehem PA (SPX) May 21, 2015
Researchers at Lehigh University have identified for the first time that a performance gain in the electrical conductivity of random metal nanowire networks can be achieved by slightly restricting nanowire orientation. The most surprising result of the study is that heavily ordered configurations do not outperform configurations with some degree of randomness; randomness in the case of metal nanowire orientations acts to increase conductivity. The study, Conductivity of Nanowire Arrays under Rando ... read more
