  1. 1. Electron Transport in Semiconductor Nanowires

    Författare :Mikael Björk; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heterostructures; single electron transistors; resonant tunneling; quantum dots; weak antilocalization; Halvledarfysik; field effect transistors; Semiconductory physics; Fysicumarkivet A:2004:Björk; Low-dimensional structures; nanowires; chemical beam epitaxy;

    Sammanfattning : In this thesis, semiconductor nanowires are studied from the point of view of growth and electrical properties. The growth of nanowires is done by chemical beam epitaxy (CBE), an ultra-high vacuum technique allowing a precise control of precursor deposition and low growth rates. LÄS MER

  3. 2. Modelling Allelic and DNA Copy Number Variations using Continuous-index Hidden Markov Models

    Författare :Susann Stjernqvist; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hidden Markov models; DNA copy number; allelic copy number; Markov chain Monte Carlo;

    Sammanfattning : In human cells there are usually two copies of each chromosome, but in cancer cells abnormalities could exist. The differences consist of segments of chromosomes with an altered number of copies. There can be deletions as well as amplifications and the lengths of the segments can also vary. LÄS MER

  4. 3. Optical spectroscopy of InGaAs quantum dots

    Författare :Arvid Larsson; Per Olof Holtz; Artur Zrenner; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; quantum dot; semiconductor; optical properties; spin; transport; wetting layer; polarization; kvantprick; halvledare; optiska egenskaper; spin; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik; Materials science; Teknisk materialvetenskap; Condensed matter physics; Kondenserade materiens fysik; Semiconductor physics; Halvledarfysik;

    Sammanfattning : The work presented in this thesis deals with optical studies of semiconductor quantum dots (QDs) in the InGaAs material system. It is shown that for self-assembled InAs QDs, the interaction with the surrounding GaAs barrier and the InAs wetting layer (WL) in particular, has a very large impact on their optical properties.

  5. 4. Costs and benefits of immune system activation on physiology, behavior and offspring phenotype from an immunoecological perspective

    Författare :Sandra Sköld Chiriac; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; immunoecology; acute-phase response; sickness behaviors; energy expenditure; fever; hypothermia; life history; maternal effects; terminal investment; costs of immune responses; Taeniopygia guttata; Parus major; Cyanistes caeruleus;

    Sammanfattning : Pathogen challenges and host immune defenses can have substantial impact on life history patterns of animals. Biotic and abiotic factors may affect immunity in wild animals, influencing e.g., population dynamics and sexual selection. LÄS MER

  7. 5. Customer value in commercial experiences : Expecting the unexpected

    Författare :Maria Eriksson; Håkan Wiklund; Ingela Bäckström; Pernilla Ingelsson; Su Mi Park-Dahlgaard; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Commercial Experience; Customer Value; Hedonic Value; Quality; Experiential quality; TQM; Kano model; Attractive Quality; Co-creation; Storytelling; Strong Engagement; Kommersiell upplevelse; Kundvärde; Njutnings- upplevelseinriktat värde; Kvalitet; Upplevelsekvalitet; TQM; Kano-modellen; Attraktiv kvalitet; Samskapa; Storytelling och Starkt engagemang;

    Sammanfattning : To an ever greater extent, customers desire experiences that are highly emotional, personally designed and memorable. Today’s customer has an increasing need to be entertained and often searches for pleasurable offerings of hedonic value. LÄS MER
