Macroscopically Ordered Thin Films of an Organic Salt Grown by Low Pressure Organic Vapor Phase Deposition
Abstract
We demonstrate the process of low pressure organic vapor phase deposition (LP-OVPD) for the growth of crystalline thin films of the organic charge transfer salt 4'-dimethylamino-N-methyl-4-stibazolium tosylate (DAST) on amorphous TiO2 substrates. LP-OVPD grown films exhibit polycrystallinity with long range structural ordering limited only by substrate size. Film surface coverage and macroscopic ordering are strongly determined by floe preparation of the TiO2 surface prior to growth. The morphology and ordering of the films are also found to depend on the deposition temperature and the composition of the precursor molecules. These results suggest that LP-OVPD films are of sufficient quality for use in optical waveguide and related photonic devices.
