Photo Conductivity of Liquid Tetramethylsilane
Very few investigations have been carried out so far on the direct photo ionization of non-polar liquids. Vermeil et al. [1] detected an increase of conductivity in some liquid hydrocarbons when subjected to the light of rare gas resonance lamps. Recently similar experiments were performed by Casanovas and co-workers at the University of Toulouse [2, 3]. It was estimated that the ionization thr...
متن کاملStudy of Photo-Conductivity in MoS2 Thin Films Grown in Low-Temperature Aqueous Solution Bath
An experimental study over the optical response of thin MoS2 films grownby chemical bath deposition (CBD) method is presented. As two important factors, theeffect of bath temperature and growth time are considered on the photocurrentgeneration in the grown samples. The results show that increasing the growth time leadsto better optical response and higher difference betw...
متن کاملIncreasing Diamonds
A class of diamond-shaped combinatorial structures is studied whose enumerating generating functions satisfy differential equations of the form f2 “ Gpfq, for some function G. In addition to their own interests and being natural extensions of increasing trees, the study of such DAG-structures was motivated by modelling executions of seriesparallel concurrent processes; they may also be used in ...
متن کاملRendering Diamonds
Fascinating colors of diamonds are generated by a combination of mechanisms including Fresnel reflection, volume absorption and light dispersion. This paper proposes an approach to unify these mechanisms to synthesize realistic computer images of diamonds. Our work is based on a composite spectral model that accounts separately for smooth components and spikes in spectra. While sufficiently han...
