Show affiliationsAn ordered array of n-type semiconductor spheres was interfaced with a matrix of p-type material to realize a distributed structure with face-centre-cubic symmetry. Both types have been realized by the use of functionalized single walled carbon nanotubes. The structures lack typical dc junction characteristics because of connectivity between p-type regions. They exhibit nonlinear optical characteristics (ac effect), which was attributed to the quadratic Stark effect.
