    Sammanfattning : Artificial light surrounds us in a manifold of shapes. It is mainly utilized for illumination, but also for graphical communication of complex and evolving messages and information, among other things. It can be generated in different ways with incandescent lamps and fluorescent tubes constituting two common examples. LÄS MER

    Sammanfattning : Molecular electronics is an area of micro/nanoelectronics with a number of farreaching goals and challenges: denser implementation of electronic memory and logic, less expensive manufacturing, smaller or more sensitive measurement devices, selfassembly of devices and systems and, last but not least, exploring new science and applications.In recent years, molecular electronics has expanded into a broader field of molecular-scale electronics, partly because molecular components have to be defined in solid-state contexts via lithography and self-assembly, and effectively become hybrid devices with new and interesting properties.

  3. 13. Photoluminescence Studies of Single Quantum Dots

    Författare :Nikolay Panev; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stranski-Krastanow; photoluminescence; laser spectroscopy; antibunching; random telegraph noise; blinking; Physics; Fysik; Fysicumarkivet A:2004:Panev; solid immersion lens; quantum dots; low-dimensional structures;

    Sammanfattning : This thesis presents photoluminescence (PL) spectroscopy studies of single III-V semiconductor quantum dots (QDs). The electronic properties of the QDs, as well as, the dynamics of the processes taking part inside and in the surroundings of the QDs have been studied by single quantum dot photoluminescence spectroscopy, time resolved spectroscopy, and correlation spectroscopy.

  4. 14. Electronic transitions and correlation effects : From pure elements to complex materials

    Författare :Johan Jönsson; Igor A. Abrikosov; Marcus Ekholm; Sergei Dudarev; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electronic transition; solid state physics; condensed matter physics; correlation effects;

    Sammanfattning : Macroscopic properties of real materials, such as conductivity, magneticproperties, crystal structure parameters, etc. are closely related or evendetermined by the configuration of their electrons, characterized by electronicstructure. By changing the conditions, e.g, pressure, temperature, magnetic/electric field, chemical doping, etc. LÄS MER

  5. 15. Unveiling the nature of dark matter with direct detection experiments

    Författare :Vanessa Zema; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NaI; phenomenology; annual-modulation; direct-detection; cryogenics; COSINUS; polarised-nuclei; CRESST; dark-matter; phonons;

    Sammanfattning : The desire of discovery is an anthropic need which characterises and connects the human being over the eras. In particular, observing the sky is an instinctive drive exerted by the curiosity of the mysteries which it retains. LÄS MER
