Organic and Polymer Crystalline Films for Spatial Light Modulation

Abstract

In this report, the work done during the last phase of this program is described. The efforts involved two components of the program in polymeric ultrathin films, second; harmonic generation measurements to characterize the second order nonlinearities, and capacitance measurements of deposition quality and water entrapment during deposition. With regard to second harmonic generation, the components of x (2) and the molecular orientation in Langmuir/ Blodgett films of hemicyanine dye on glass substrates are reported. Decay of the signal because of molecular rearrangement and diffusion of impurities is discussed. For the capacitance sensor, subphase (water) entrainment is described as a function of deposition speed and of material composition.
