    Sammanfattning : Abundant proprioceptive information originates in eye and neck muscles but their role in normal visual function is unknown. Under experimental conditions, proprioceptive activation induces illusory visual movement, whereas clinical evidence indicates that proprioceptive dysfunction causes disturbances in spatial orientation.

  2. 2. Optical Properties of Low Dimensional Semiconductor Materials

    Författare :Tiantian Han; Ying Fu; Per-Olof Holtz; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Semiconductor; Low dimensional; optics; Physics; Fysik;

    Sammanfattning : This dissertation presents a serial study on optical properties of different semiconductor materials. Three main types of studies are addressed: The role of doping levels of N and Al atoms in the room-temperature photoluminescence (PL) of 4H-SiC films for optoelectronic applications; the use of a basic Monte Carlo method combined with probability calculations of the time-dependent Schroedinger equation to manifest multi-photon absorption and emission of II-VI compound quantum dots (QDs) for bioimaging; a theoretical quantum chemistry approach to study of structure and optical properties of InGaAsN and GaAs clusters for laser technology applications.
