Dependence of Off-Diagonal Components of χ⁽³⁾ on Substrate Temperature of Epitaxially Grown Vanadyl Phthalocyanine Films

Abstract

Optically polarized light micrographs of isothermally melt-textured DyBa 2 Cu 3 O 7−δ compounds (with 15 wt% Dy 2 O 3 addition) are presented to show evidence for pattern formation of DyBa 2 Cu 3 O 5 particles in DyBa 2 Cu 3 O 7−δ grains. Different types of pattern were observed and were understood as arising from the crystal growth mechanism of 123 melt-textured materials. In an appendix, the case of patterns in magnetically textured samples is discussed.

Ultrathin Organic Films Grown by Organic Molecular Beam Deposition and Related Techniques

“…These new developments must also be placed in the context of long efforts and progress which has been directed at employing organic thin films for solar energy conversion , and in sensors of various kinds. Finally, vacuum-deposited OMCs have also been proposed as materials with large second- or third-order optical nonlinearities, ,− ,,,,,− or large χ (3) . There are, in addition, many, somewhat less conventional uses of organic thin films deposited in vacuum, including waveguides and optical couplers, ,,, organic/inorganic photodetectors, , lasers, etc.…”

Nonlinear Optical Characteristics of Vanadyl Phthalocyanine Thin Film Grown by the Molecular Beam Epitaxial Method

“…The substrate temperature during deposition was maintained around 70°C, because this condition affords a relatively good film quality according to our previous study. 19 The characterization of film structure was carried out by scanning and transmission electron microscopy. 1,2 Nonlinear Optical Measurement.…”

“…VOPc source was heated to ∼350 °C to achieve a deposition rate of 1 Å/min. The substrate temperature during deposition was maintained around 70 °C, because this condition affords a relatively good film quality according to our previous study , …”

High mobility polymer gated organic field effect transistor using zinc phthalocyanine

“…The basic properties of many metal phthalocyanines have been studied in detail by various researchers (Gould 1985;Belgachi and Collins 1998). They also exhibit strong non-linear optical properties, due to their spatially extended π -electron system (Fang et al 1993). In order to utilize the mechanical flexibility inherently possessed by organic materials, many attempts have been made to develop polymeric gate dielectric layers.…”
