  3. 3. Time-resolved x-ray diffraction of nanostructured samples

    Författare :A. I. H. Persson; Atomfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; x-ray diffraction; phonons; optoacoustic transducer; electron diffusion; nanowires; Fysicumarkivet A:2016:Persson;

    Sammanfattning : The work presented in this thesis is based on time-resolved x-ray diffraction studies of InSb (111) samples. The experiments were carried out using a pump-probe configuration using short laser pulses as the pump and x-rays as the probe. Laser excitation leads to the formation of a strain pulse that propagates through the sample. LÄS MER
