A simple vapor‐assisted in‐plane epitaxial growth method generated a highly oriented zif‐95 membrane.
The oriented character of the shish‐kebab fibers results in polarized optical absorption and photoluminescence. The formation of oriented precursors by epitaxial orientation of polymer chains onto long needles of a molecular crystal—tcb in the present case—appears to be an original alternative to the crystallization usually performed under external flow conditions.

High-quality organic semiconductor crystals are usually grown by a lab solution method, by which it is difficult to fabricate crystal arrays on the substrate, let alone achieve industrial production. Therefore, in this work, oriented single crystal arrays have been prepared by epitaxial growth. As an example, 2,7-dioctyl [1]benzothieno [3,2- b ]benzothiophene (c8-btbt) was spin-coated on the surface of a highly oriented melt-drawn isotactic polypropylene (ipp) film on 300 nm sio 2 substrates.

Epitaxial bbto thin films were deposited on the single crystal nb-doped (1 0 0) srtio 3 substrates. By controlling the growth rate, it was possible to change the growth mode from the grain growth mode to the layer-by-layer growth mode. Thus, it was possible to grow the bbto thin films with improved crystallinity along the c-orientation. It was confirmed that the bbto thin films have good ferroelectric properties by various measurements such as leakage current characteristics, ferroelectric.

Epitaxy refers to a type of crystal growth or material deposition in which new crystalline layers are formed with one or more well-defined orientations with respect to the crystalline substrate. The deposited crystalline film is called an epitaxial film or epitaxial layer. The relative orientation of the epitaxial layer to the crystalline substrate is defined in terms of the orientation of the crystal lattice of each material. For epitaxial growth, the new layer must be crystalline and each crys.
