  1. 1. Computations of the Perpendicular Magnetic Anisotropy Energy of Permalloy

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Luca Mikadze; [2022]
    Keywords : permalloy; perpendicular magnetic anisotropy; perpendicular magnetic anisotropy energy; magnetocrystalline anisotropy; magnetocrystalline anisotropy energy; thin film; density functional theory;

    Abstract : Magnetic materials have many applications in technology. The magnetic properties of materials are therefore important to catalogue for future use. In this project, the magnetic properties of thin films of permalloy are investigated. READ MORE

  2. 2. Homebuilt reactor design and atomic layer deposition of metal oxide thin films

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Pamburayi Mpofu; [2021]
    Keywords : Thin films; atomic layer deposition;

    Abstract : This research thesis covers work done on building an atomic layer deposition (ALD) reactor followed by the development and optimization of an ALD process for indium oxide thin films on crystalline silicon substrates from new precursors using this new homebuilt cost-effective tool. This work describes the design, building and testing of the ALD system using an indium triazenide precursor and water in a novel precursor combination. READ MORE

  3. 3. Implementation of Scheimpflug Lidar for Entomological Monitoring of Bark Beetles

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Jonathan Peterson; [2020]
    Keywords : Scheimpflug Lidar; Lidar; Bark beetles; Forestry; Entomological monitoring; Physics and Astronomy;

    Abstract : Bark beetles are responsible for great damages to Swedish forestry every year. This project focuses on a method of entomological lidar called Scheimpflug lidar to detect and monitor bark beetles. Scheimpflug lidar uses old techniques from photography to achieve a deep field of focus to resolve objects over long distances. READ MORE

  4. 4. Sputtering of High Quality Layered MoS2 films

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Sari Abid Al Shaybany; [2020]
    Keywords : MoS2; molybdenum; molybdenum disulfide; sputtering; magnetron sputtering; high quality; sulfur; H2S; argon; pressure; temperature; high temperature; monolayer; few layers; large scale;

    Abstract : We have deposited bulk, monolayer and few-layers as well as large-scale 2D layered MoS2 thin films by pulsed DC magnetron sputtering from an MoS2 target. MoS2 has gained great attention lately, together with other layered Transition Metal Dichalcogenides (TMDCs), for its unique optical and electrical properties with thickness-dependent bandgap.

  5. 5. A comparative study of ZnO i-layer deposited with ALD and PVD for CIGS solar cells

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Joel Johansson Byberg; [2019]
    Keywords : CIGS; ZnO; ZnMgO; solar cells; thin film; zinc oxide; window layer; ALD; PVD;

    Abstract : Two identified setbacks for CIGS based devices in order to obtain higher efficiency are parasitic absorption in the window layer structure and losses in open-circuit voltage due to bad interfaces. This study investigated how the performance of the solar cell is affected by depositing intrinsic ZnO (i-ZnO) and ZnMgO with atomic layer deposition (ALD) instead of the conventional sputtering.
