Abstract: An organic thin film includes an organic crystalline phase, where the organic crystalline phase defines a surface having a surface roughness (Ra) of less than approximately 10 micrometers over an area of at least approximately 1 cm2. The organic thin film may be manufactured from an organic precursor and a non-volatile medium material that is configured to mediate the surface roughness of the organic crystalline phase during crystal nucleation and growth. The thin film may be formed using a suitably shaped mold, for example, and the non-volatile medium material may be disposed between a layer of the organic precursor and the mold during processing.

Abstract: A thin film assembly includes an optical thin film and a discontinuous spacer layer disposed over a major surface of the optical thin film. Within a multilayer stack of optical thin films, the spacer layer may be located between opposing regions of adjacent thin films such that the spacer layer separates the adjacent thin films and inhibits or prevents surface-to-surface contact.

Abstract: A mechanically and piezoelectrically anisotropic polymer thin film is formed from a crystallizable polymer and an additive configured to interact with the polymer to facilitate chain alignment and, in some examples, create a higher crystalline content within the polymer thin film. The polymer thin film and its method of manufacture may be characterized by a bimodal molecular weight distribution where the molecular weight of the additive may be less than approximately 5% of the molecular weight of the crystallizable polymer. Example polymers may include vinylidene fluoride, trifluoroethylene, chlorotrifluoroethylene, hexafluoropropylene, and vinyl fluoride. Example additives may occupy up to approximately 60 wt. % of the polymer thin film. The polymer thin film may be characterized by a piezoelectric coefficient (d31) of at least approximately 5 pC/N or an electromechanical coupling factor (k31) of at least approximately 0.1.

Abstract: A method of forming an organic solid crystal (OSC) thin film includes forming a layer of a non-volatile medium material over a surface of a mold, forming a layer of a molecular feedstock over a surface of the non-volatile medium material, the molecular feedstock including an organic solid crystal precursor, forming crystal nuclei from the organic solid crystal precursor, and growing the crystal nuclei to form the organic solid crystal thin film. An organic solid crystal (OSC) thin film may include a biaxially-oriented organic solid crystal layer having mutually orthogonal refractive indices, n1≠n2≠n3.

Abstract: A method of forming a uniaxially oriented crystalline polymer article includes heating a segment of a crystallizable polymer article to a first temperature, applying a stress to the crystallizable polymer article in an amount effective to induce a positive strain within the segment of the crystallizable polymer article, and heating the segment of the crystallizable polymer article to a second temperature greater than the first temperature while continuing to apply the stress.

Abstract: A multilayer reflective polarizer includes a layer of a birefringent organic solid crystal, where the birefringent organic solid crystal has a refractive index of at least approximately 1.5 and a birefringence of at least approximately 0.1. The multilayer reflective polarizer may be configured to include alternating layers of a birefringent organic solid crystal material and a secondary material layer selected from an amorphous polymer, an inorganic amorphous compound, a liquid crystal, and an OSC material. The refractive index of the birefringent organic solid crystal layer(s) may be modified through the application of an applied voltage, current, or stress.
