Journal ArticleDOI
Linear and nonlinear optical spectra of polyazomethines fabricated by chemical vapor deposition
TL;DR: In this paper, the results of third-harmonic generation (THG) measurements on vapor-deposited thin films of two polyazomethines, poly(nitrilo-1,4-phenylenenitrilomethylidyne-1.4-photon resonance centered near 0.9 eV for both samples; additional weaker structure is observed for PNPP near 1.2 eV.

Smart polymer image processor
TL;DR: In this paper, a smart array is defined as a conducting polymer device which provides local gain adjustment for video display such that the entire sensor dynamic range available, typically more than 16 bits in the infrared detector case, can be utilized locally to solve the intra-scene contrast problem.

TL;DR: The utility of pd-pcAFM is demonstrated to investigate the optical/structural anisotropy that exists within a well-performing BHJ system and its relationship to optoelectronic properties on both the nanometer and micrometer length scales.
Journal ArticleDOI
Metal-insulator transition in an organic solid: Experimental realization of the one-dimensional Hubbard model
TL;DR: In this article, the authors present an experimental study of a metal-insulator transition in an organic molecular solid, in terms of the exact theoretical ground state results and the projected theoretical temperature dependence, showing that the NMP-TCNQ system is a nearly ideal example of the Hubbard model in one dimension.
