  5. 4. Electron Energy Loss Spectroscopy of III-Nitride Semiconductors

    Författare :Justinas Palisaitis; Per Persson; Lars Hultman; Jens Birch; Ernesto Coronel; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : This Licentiate Thesis covers experimental and theoretical investigations of the bulk plasmon response to different compositions and strain states of group III-nitride materials. Investigated materials were grown using magnetron sputtering epitaxy and metal organic chemical vapour deposition and studied by Rutherford backscattering spectrometry, X-ray diffraction, electron microscopy and electron energy loss spectroscopy (EELS).
