    Abstract: The THz waveguides disclosed herein are used to transmit signals having a THz frequency in the range from 0.1 THz to 10 THz and include an alumina core surrounded by an optional cladding. The core may have a diameter (D1) in the range from 10 μm to 500 μm and may be comprised of a ceramic ribbon having a dielectric constant (Dk). The optional cladding may have a dielectric constant (Dk) less than the core. The THz waveguides can be formed using a continuous firing process and nano-perforation technology that enables access to a wide form factor range. In one example, rectangular waveguides, or ribbons, may be fabricated in the 10 μm to 200 μm thick range at widths in the range from sub-millimeters to several meters and lengths in the range from millimeters to several hundred meters.

    Abstract: Disclosed is a polymer blend comprising an organic semiconductor (OSC) polymer blended with an isolating polymer and method for making the same. The OSC polymer includes a diketopyrrolopyrrole fused thiophene polymeric material, and the fused thiophene is beta-substituted. The isolating polymer includes a non-conjugated backbone, and the isolating polymer may be one of polyacrylonitrile, alkyl substituted polyacrylonitrile, polystyrene, polysulfonate, polycarbonate, an elastomer block copolymer, derivatives thereof, copolymers thereof and mixtures thereof. The method includes blending the OSC polymer with an isolating polymer in an organic solvent to create a polymer blend and depositing a thin film of the polymer blend over a substrate. Also disclosed is an organic semiconductor device that includes a thin semiconducting film comprising OSC polymer.
