  1. 1. Structural analysis of HZO thin film and electrode using X-ray diffraction

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

    Author : Elliot Winsnes; [2024]
    Keywords : HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Abstract : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. READ MORE

  3. 2. Humidity dependent conductivity of air in HVDC applications and the role of surfaces

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Erik Svensson; [2023]
    Keywords : HVDC; humidity; air conductivity; thin films; HVDC; luftfuktighet; luftkonduktivitet; tunna filmer;

    Abstract : High Voltage Direct Current (HVDC) bushings are insulated devices designed to facilitate the safe passage of electric current across an earthed barrier. Understanding air conductivity is of utmost importance in the design of HVDC components, which is determined by ion density and ion mobility. READ MORE

  4. 3. Crystallinity of Sputtered TiO2 Thin Films: a Study of the Heating and Plasma Influence on the Growth

    University essay from

    Author : oussama ezzaher; [2023]
    Keywords : ;

    Abstract : AbstractHigh-Power Impulse Magnetron Sputtering (HIPIMS) of TiO2 thin films enhances their photocatalyticproperties compared to the films prepared by standard sputtering methods, especially when no substrateheating is employed. With no heating, the coatings present an amorphous structure that benefits from theionization of the sputtered flux granted by HiPIMS, with respect to their photocatalytic performance. READ MORE

  5. 4. (1,3-di-tert-butyltriazenide) Cu(I) as vapor deposition precursor

    University essay from Linköpings universitet/Kemi

    Author : Peggy Bagherzadeh; [2023]
    Keywords : Vapor deposition; CVD; ALD; triazenide;

    Abstract : In the past few decades, devices such as computers have become smaller, and their performance has improved beyond comparison. Semiconductors and interconnectors are used in almost all devices today and are made of thin films. READ MORE

  6. 5. A Quantum Chemical Investigation of Chemical Vapour Deposition of Fe using Ferrocene and Plasma Electrons

    University essay from Linköpings universitet/Kemi

    Author : Felicia Andersson; [2023]
    Keywords : Quantum chemistry; Ferrocene; Silver; Ag 111 ; Plasma electrons; Surface chemistry; Electronic structure; DFT; Kvantkemi; Ferrocen; Silver; Ag 111 ; Plasmaelektroner; Ytkemi; Elektronstruktur; DFT;

    Abstract : Thin films provide a remarkable asset, as depositing a thin surface layer can completely alter a material’s characteristics and provide new, inexpensive, and valuable properties. In 2020, a new Chemical Vapour Deposition (CVD) approach was developed at Linköping University, using plasma electrons as reducing agents for the deposition of metallic thin films. READ MORE
