  1. 1. The Effect of Temperature Gradients During Intercritical Annealing of Advanced High Strength Steels : Method Development for Experimental Streamlining

    University essay from KTH/Materialvetenskap

    Author : Helena Ek Jendrny; [2023]
    Keywords : AHSS; Gleeble; Intercritical annealing; Retained austenite; Medium Mn Steel; AHSS; Gleeble; interkritisk glödgning; austenit; Medium Mn stål;

    Abstract : The third-generation advanced high strength steels, AHSS, represent an opportunity for today’s steel development, where lighter materials with maintained strength and toughness are in demand. The unique properties of these materials often stem from a tailored microstructure. READ MORE

  3. 2. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Hamish Keay; [2023]
    Keywords : Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

    Abstract : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. READ MORE

  4. 3. Flashlamp Annealing for Improved Ferroelectric Junctions

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Theodor Blom; [2023]
    Keywords : Flashlamp annealing; ferroelectricity; hafnia oxide; III-V semiconductor; thermal annealing; device performance; Technology and Engineering;

    Abstract : The effects of flashlamp annealing (FLA) on the quality of ferroelectric HfxZr1–xO2 (HZO) interfaces, integrated on InAs substrates, are evaluated. For the integration of ferroelectric HZO on III-V semiconductors the crystallization via rapid thermal processing (RTP) can severely degrade the HZO/III-V interface. READ MORE

  5. 4. BCP Lithography Defined Arrays of InAs NWs Grown Using MOVPE with Au Seeds

    University essay from Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/Fasta tillståndets fysik

    Author : Björn Landeke-Wilsmark; [2022]
    Keywords : Physics and Astronomy;

    Abstract : In this report we outline a detailed process flow for a quick and inexpensive implementation of large dense arrays of InAs nanowires (NWs) grown in the reactive ion etching/etched (RIE) pores of a SiO2/SiNx mask on top of an InAs/Si(111) substrate. The self-assembled (hexagonally close-packed) pattern of poly(methyl-methacrylate) (PMMA) cylinders in a poly(styrene) (PS) matrix adopted by a linear diblock poly(styrene-block-methyl-methacrylate) P(S-b-MMA) block-copolymer (BCP) was transferred to the dielectric stack (consisting of a ≈10 nm plasma enhanced chemical vapour deposition/deposited (PECVD) SiNX layer topped by a thin atomic layer deposition/deposited (ALD) SiO2 film) using a two-step RIE procedure.

  6. 5. Laminated HZO on InAs: A study of as-deposited ferroelectricity

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : André Andersen; [2022]
    Keywords : Ferroelectricity; HZO; InAs; III V; As-deposited ferroelectricity; BEOL; Nanoelectronics; Nanoprocessing; Nanotechnology; ALD; MOSCAP; Memory Technology; Technology and Engineering;

    Abstract : As the limits of transistor feature size scaling is reaching its saturation, new innovations are needed to prevent performance loss. High performance transistors on the III/V semiconductor platform implemented with ferroelectric oxides might in the future satisfy this demand. READ MORE
