  3. 2. Growth and structural characterization of GaP-GaPSb nanowires

    University essay from Lunds universitet/Atomfysik

    Author : Dario Stjärnemyr Ghidini; [2012]
    Keywords : Material Science; Nanowire; GaPSb; Physics and Astronomy; Chemistry; Technology and Engineering;

    Abstract : In this thesis epitaxial growth of Ga(P1-xSbx) and analysis by electron microscopy are presented. To the authors knowledge Ga(P1-xSbx)has not been grown in the form of nanowires before and the main motivation of this work is to investigate the possibility of overcoming the miscibility gap (1-99%) in nanostructures.

  4. 3. Spinodal Decomposition in the Binary Fe-Cr System

    University essay from KTH/Metallografi

    Author : Saeed Baghsheikhi; [2009]
    Keywords : Fe-Cr binary system; phase diagram; miscibility gap; spinodal decomposition; nucleation and growth; hardness; TEM; contrast modulations;

    Abstract : Spinodal decomposition is a phase separation mechanism within the miscibility gap. Its importance in case of Fe-Cr system, the basis of the whole stainless steel family, stems from a phenomenon known as the “475oC embrittlement” which results in a ruin of mechanical properties of ferritic, martensitic and duplex stainless steels.
