A fabrication process (plasma and wet etching of Si, lift off technology) is developed for polycrystalline Si strip-like waveguides (220 nm thick), waveguide lamellar diffraction grating and 2D photonic crystal structures tuned to an electromagnetic wave with the wavelength 1.5 µm. The photonic crystals are composed of either Si pillars or pores in a Si waveguide which is situated on the surface of...
Copper polyphthalocyanine (CuPPC), a 2D conjugated polymer, is a promising material for electronics and photovoltaics, but its applications were hindered by a poor processability. We propose an experimental approach, by which thin films of CuPPC, can be directly synthesized in a chemical vapor deposition (CVD) set-up at mild temperature (420°C). High polymerization degree and high crystallinity of...
