  1. 11. Digital Timing Generator for Control of Plasma Discharges

    University essay from Linköpings universitet/Elektroniska Kretsar och System

    Author : Hao Hsiang Liao; [2019]
    Keywords : High-Power Impulse Magnetron Sputtering HiPIMS ; Thin Film Technology; Synchronization System design; Microcontroller Unit MCU ; Field-programmable Gate Array FPGA ;

    Abstract : This thesis report presents a new design of a synchronization unit for high power impulse magnetron sputtering (HiPIMS) applications used for depositing thin films. The proposed system is composed of two major hardware parts: a microcontroller unit (MCU) and a field-programmable gate array (FPGA). READ MORE

  3. 12. Investigation of thermal conductivity in thin graphite films through time-resolved X-ray diffraction

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

    Author : Axel Stenquist; [2019]
    Keywords : Ultra fast X-ray diffraction; graphite; thin graphite films; thermal conductivity; Physics and Astronomy;

    Abstract : Knowledge about thermal properties of nanoscale graphite is essential in order to realize the many promising applications of carbon based nanomaterials. This thesis reports how samples of thin graphite films on nickel substrates were investigated using time-resolved X-ray diffraction (TRXD) at the FemtoMAX beamline at the MAX IV facility. READ MORE

  4. 13. Characterization of combinatorial Cu2ZnSnS4 thin films

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Joakim Adolfsson; [2018]
    Keywords : Photovoltaics; Kesterite; Material science; Raman; Photoluminescence;

    Abstract : The kesterite Cu2ZnSnS4 (CZTS) is considered as a possible absorber layer in future photovoltaic (PV) applications. The abundance of its constituent elements along with the material being non-toxic and having a direct band gap of around 1.5 eV make it an attractive material for solar cell applications. So far, cells with an efficiency of 12. READ MORE

  5. 14. Kinetic Monte-Carlo studies of island shape evolution on weakly-interacting substrates

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

    Author : Filip Thunström; [2018]
    Keywords : Kinetic Monte Carlo; thin film; metal; weakly interacting substrates;

    Abstract : Metal thin films deposited on weakly-interacting substrates constitute an essential element of numerous microelectronic, catalytic, and optical devices. However, the natural tendency of metal atoms to agglomerate, upon condensation on a weakly-interacting surface, in dispersed three-dimensional (3D) islands affects negatively the performance of the above-mentioned devices.

  6. 15. Ferroelectricity in nanocrystalline Hf0.5Zr0.5O2 thin films

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

    Author : Lun Sang; [2018]
    Keywords : ferroelectricity; Hf0.5Zr0.5O2; GIXRD; XRR; Technology and Engineering; Physics and Astronomy;

    Abstract : Hafnium dioxide (HfO_2) based thin films doped with various dopants (Si, Ge, Al, Gd, Sr, Zr) have been found to exhibit ferroelectricity. These dopants were found to stabilize the III orthorhombic phase in the hafnium oxide based thin films. READ MORE
