  1. 1. Investigations of Optical Properties and Photo-Alignment in Bistable Nematic Liquid Crystal Displays

    Författare :Jesper Osterman; Claes-Göran Granqvist; Kent Skarp; Peter Raynes; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; LCD; liquid crystal; bistable; nematic; optical; modes; photo-alignment; Teknisk fysik; Engineering physics; Teknisk fysik;

    Sammanfattning : In recent years portable electronic devices, such as mobile phones and personal digital assistants, have increased the demand for high performance displays with low power consumption. An interesting candidate with the potential of fulfilling these demands is the reflective single-polarizer surface controlled bistable twisted nematic liquid crystal display. LÄS MER

    Sammanfattning : Good knowledge about optics and surface physics of liquid crystals is indispensable when utilising them for applications, such as liquid crystal displays (LCDs). However, they are also two central subjects in fundamental research on liquid crystals. LÄS MER

  7. 5. Quantum Wavepacket Dynamics in Molecular and Trapped Ion Systems

    Författare :Dong Wang; Tony Hansson; Volker Engel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wavepacket; revival; anisotropy; polarization; Molecular physics; Molekylfysik; kemisk fysik; Chemical Physics;

    Sammanfattning : The motions of a wavepacket in the two coupled potentials studied in this thesis can be classified into either bistable or astable motion according to the wavepacket interference at the curve crossing. Bistable motion, in which the wavepacket performs a coupled oscillation but remains in the same adiabatic and diabatic state, can exist both in bound-bound systems and bound-unbound ones with long time stability.
