Organic Electro-optic Single- Crystalline Thin Films Grown Directly on Modified Amorphous Substrates

High quality organic electro‐optic single crystalline thin films are produced on amorphous C≡N‐modified glass substrates (see figure), which is a mimic surface of a crystal, by slow evaporation and capillary methods. The films have a suitable size (shaped as rectangular plates with side lengths in the range of 5–10 mm and regular thicknesses in the range of 1–40 μm) for the fabrication of photonic devices.
