    Författare :Fariba Ferdos; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gender; InAs quantum dots; SiC diode; engineer; online learning.; self-organised quantum dots; engineering education; pedagogy; molecular beam epitaxy; group work; cross-cultural study; quantum dot lasers;

    Sammanfattning : This thesis builds on new cross-disciplinary research between engineering and educational sciences. Recently, two other theses that combine research in physics and education (Åke Ingerman, 2002, and Tom Adawi, 2002) have been completed in Sweden. This thesis consolidates a trend that can benefit both disciplines. LÄS MER

  4. 3. Novel Technologies for Mode-Locking of Solid-State Lasers

    Författare :Niels Meiser; Valdas Pasiskevicius; Steinmeyer Günter; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; laser; mode-locked laser; pulsed laser; quantum dot; carbon nanotube; nonlinear optics; saturable absorber; Kerr-lens mode-locking; ultra-fast laser; picosecond laser; pulsed laser; semiconductor saturable absorber;

    Sammanfattning : The subject of this thesis is the investigation of novel technologies for mode-locking of diode-pumped, solid-state lasers. Novel saturable absorbers are used: quantum dots (QDs) and carbon nanotubes (CNTs), which both are low-dimensional nano-formations. In addition, mode-locking by cascaded nonlinearities is explored.

  5. 4. Carrier dynamics in semiconductor quantum dots

    Författare :Jörg Siegert; Ari Friberg; Jesper Mørk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; quantum dots; photoluminescence; time-resolved; spectroscopy; semiconductor; Optics; Optik;

    Sammanfattning : This thesis presents results of time-resolved photoluminescence experiments conducted on several different self-assembled InGaAs/GaAs and InAs/GaAs semiconductor quantum dot (QD) structures. Depending on the application in mind, different structural, electronic or optical properties have a different weight of importance. LÄS MER
