  1. 1. On the Optics and Surface Physics of Liquid Crystals

    Författare :Pontus Jägemalm; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; deformed helix; anchoring; short-pitch; SiO; homogeneous models; two-fold degenerate alignment; Berreman; bistable alignment; optical activity;

    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

  5. 4. Tunnel Emitter Transistors

    Författare :Erik Aderstedt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TET; tunneling; siO2< sub>; tunnel emitter transistor; MOS; Ta2< sub>O5< sub>; silicon; high- #954; BICFET; dielectrics;

    Sammanfattning : The Tunnel Emitter Transistor is based on the modulation of the tunnel current in a Metal Oxide Semiconductor (MOS) structure with an ultra-thin oxide layer. The modulation is accomplished by injecting charge to the oxide-semiconductor interface from a third terminal. LÄS MER

  7. 5. High Resolution Studies of Circumstellar Masers

    Författare :Francisco Colomer Sanmartin; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis describes in detail the observational procedures that we have followed and developed to analyze several research projects organized at Onsala since 1990 to study the regions of SiO maser emission at 43 GHz in the circumstellar envelopes of late-type stars with very high angular resolution. The compact nature of these SiO maser regions has been demonstrated in this work. LÄS MER
