  4. 7. Structures and Properties of Ferroelectric Liquid Crystal Displays

    Author : Marek Matuszczyk; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smectic; displays; dielectric anisotropy and biaxiality; surface-stabilized structure; dielectric; paraelectric; liquid crystal alignment; electroclinic effect; grey scale; polarization; multiplexing; liquid crystal LC ; orthogonal and tilted phases; chirality; aligning layer; ferroelectric; polyimide; rubbing; light valves and modulators; SSFLC;

    Abstract : Liquid crystals have unique physical properties as they combine the features of solids and liquids. In thermotropic liquid crystals the degree of order varies with temperature resulting in an appearance of intermediate phases. READ MORE

  5. 8. Controlling function by structure-intermolecular interactions and crystal engineering with N-donor ligands

    Author : Mohamed I D M Ghazzali; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; OPL; 10 phenanthroline]2 .; single crystal diffraction; intermolecular interactions; crystal engineering; Fe II coordination polymers; Schiff’s bases; porphyrins; intercalation; [ Ru tris-1;

    Abstract : In the solid state regime, crystal engineering based on non-covalent synthesis requires an intuition about the intermolecular forces that can dictate the molecular architecture. Hydrogen bonds have become an instrumental tool in the self assembly and supramolecular chemistry. READ MORE

  6. 9. On computational homogenization of gradient crystal inelasticity

    Author : Kristoffer Carlsson; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computational homogenization; gradient theory; multiscale modeling; crystal plasticity;

    Abstract : Crystal inelasticity is the main modeling technique employed to study the mechanical behavior of polycrystalline metallic materials. This class of models has the capability to represent micromechanical phenomena such as plastic slip, grain boundary interactions, and dislocation pile-up. READ MORE

  7. 10. Optical studies of crystal phase heterostructures

    Author : Irene Geijselaers; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; III-V semiconductor nanowires; photoluminescence; photoluminescence excitation; polytype; crystal phase heterostructure; InP; GaAs; wurtzite; Fysicumarkivet A:2021:Geijselaers;

    Abstract : III-V semiconductors are commonly used for a variety of optical applications, such as LED based lights and solar sells. Most III-V semiconductors, such as GaAs and InP, exhibit the zinc-blende (zb) crystal structure, but in the form of nanowires it is also possible to create them in the wurtzite (wz) crystal structure.
