Proceedings ArticleDOI
Origin, scaling, and saturation of nonlinear polarizabilities in donor/acceptor polymers
TL;DR: In this paper, the authors used a Collective Electronic Oscillator (CEO) technique to explore the variation of linear, second-and third order polarizabilities in donor/acceptor substituted polymers all the way to the bulk.
Journal ArticleDOI
