    Abstract : The global trend towards quieter environments has been one of the key topics of acoustics research for years. The recent tightening of the regulations on noise exposure as well as the many reports on the impact of noise on human health confirm this situation and stress ever more the need for innovative mitigation strategies.

  6. 4. Optical studies of AlN and GaO based nanostructures using Mueller matrix spectroscopic ellipsometry

    Author : Samiran Bairagi; Kenneth Järrendahl; Ching-Lien Hsiao; Bruno Gallas; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GLAD; MMSE; PVD; III-nitrides; Oxides; Anisotropy; Bandgap;

    Abstract : This thesis explores the diverse optical properties manifested when light interacts with various materials, with an emphasis on circular polarization- and bandgaprelated phenomena. The studies in this work are centered around Mueller matrix spectroscopic ellipsometry, with the objective of synthesizing and characterizing nanostructured and high-quality thin films to expand our understanding of the optical properties arising from their underlying structure and electronic transitions, respectively.

  7. 5. Defect-engineered (Ti,Al)N thin films

    Author : Isabella Citlalli Schramm Benítez; Frank Mücklich; Magnus Odén; Sven Ulrich; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis investigates the effect of point defects (nitrogen vacancies and interstitials) and multilayering ((Ti,Al)N/TiN) on the phase transformations in cathodic arc-evaporated cubic (Ti,Al)N thin films at elevated temperatures. Special attention is paid to the evolution of the beneficial spinodal decomposition into c-TiN and c-AlN, the detrimental formation of wurtzite AlN and the potential application as hard coating in cutting tools.
