  1. 16. Experimental Methodologies for Analyzing Austenite Recrystallization in Martensitic Tool Steels

    University essay from KTH/Materialvetenskap

    Author : Robin Nilsson; [2015]
    Keywords : Tool steels; Recrystallization; Prior austenite grain boundaries; Martensite; EBSD; Chemical etching; Thermal etching;

    Abstract : Revealing the prior austenite grain boundaries from a martensitic structure is well known to be very difficult and dependent on the chemical composition and the thermomechanical processing of the steel. In the present study, four different chemical etching reagents and additional thermal etching have been conducted for thermomechanical simulated tool steels Orvar Supreme and Stavax ESR. READ MORE

  3. 17. Development of All Dry Nanoimprint Lift-Off Process for Growth of Nanowires

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

    Author : Yasna Aberi; [2014]
    Keywords : Physics and Astronomy;

    Abstract : In this project, nanoimprint lithography has been applied to define gold particles on the surface of an InP wafer. For achieving this aim, a dry etching process has been developed to create resist undercut for the lift-off. READ MORE

  5. 19. Metal-assisted etching of nanopores in silicon

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Alexander Mörsdorf; [2014]
    Keywords : ;

    Abstract : Nanoporous membranes are an interesting approach to manufacture a variety of devices for different applications. For example in biomedicine the separation of molecules or cells or the sequence-based analysis of single-stranded DNA are of great interest. READ MORE

  6. 20. Characterization of SiGe layers grown by Trisilane and Germane at low temperatures for BiCMOS application

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Carmine Cappetta; [2014]
    Keywords : ;

    Abstract : Low temperature epitaxy (LTE) of SiGe by chemical vapor deposition (CVD) has attracted dramatic attention during the last decade for CMOS and BiCMOS application. LTE relates to a temperature range of 350÷650 °C. READ MORE
