  2. 17. Optical Properties of Low Dimensional Semiconductor Materials

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

    Abstract : 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.

    Abstract : Tailoring the surface composition and morphology of materials to enable new electronic devices is important for a wide range of applications such as quantum computing or spintronics. A fundamental understanding of the changes induced in the surface during different process steps can help to establish new synthesis routes as well as devices. READ MORE

  4. 19. Structural and elastic properties of InN and InAlN with different surface orientations and doping

    Author : Mengyao Xie; Vanya Darakchieva; Jens Birch; Enrique Calleja; Linköpings universitet; []
    Keywords : ;

    Abstract : Group–III nitrides, InN, GaN, AlN, and their alloys, have revolutionized solid state lighting and continue to attract substantial research interest due to their unique properties and importance for optoelectronics and electronics. Among the group–III nitrides, InN has the lowest effective electron mass and the highest electron mobility, which makes it suitable for high–frequency and high power devices. READ MORE
