  1. 21. Finite-size effect in CoAlZr/AlZr multilayers

    University essay from Uppsala universitet/Materialfysik

    Author : Fredrik Backer-Meurke; [2018]
    Keywords : Magnetism; thin film; Co; AlZr; Magnetic materials;

    Abstract : The structural and magnetic properties of amorphous Cox(Al80Zr20)1-x multilayers with varying thicknesses of the magnetic bilayers have been investigated. The reduction of the thickness causes a reduction of the critical temperature, Tc, this is known as the finite-size effect. READ MORE

  3. 22. Ultra-Thin Ag Films on the Sn/Si(111)-√3×√3 Surface Studied by STM

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Rasmus Lavén; [2018]
    Keywords : Silver; Silicon; Tin; Metal-semiconductor interfaces; Thin metal films; Scanning tunneling microscopy; Quantum size effects;

    Abstract : The growth of atomically flat silver films on Si(111) usually requires a two-step growth, including deposition at low temperature (≈100 K) followed by slowly annealing to room temperature. In addition, flat silver films are usually only obtained on Si(111) for film thicknesses larger than the critical thickness of 6 monolayer. READ MORE

  4. 23. Compositional gradients in sputtered thin CIGS photovoltaic films

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Daniel Boman; [2018]
    Keywords : CIGS; sputtering; GGI; Ga-grading; Thin film solar cells;

    Abstract : Cu(In,Ga)Se2 (CIGS) is a semiconductor material and the basis of the promising thin-film photovoltaic technology with the same name. The CIGS film has a typical thickness of 1-2 mm, and solar cells based on CIGS technology has recently reached efficiencies of 23.3%. READ MORE

  5. 24. Synthesis of CdZnS by Chemical Bath Deposition for Thin Film Solar Cells

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Emil Fjällström; [2017]
    Keywords : CdZnS; Chemical Bath Deposition; Thin film solar cells; CZTS; CIGS;

    Abstract : The buffer layer is a crucial component in thin film solar cells. Defects at the interface between absorber and buffer layer lead to high recombination rate and the band structure at the interface highly affects the performance of the solar cell. READ MORE

  6. 25. Metalization of Micro Fibrillated Cellulose (MFC) films

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Author : Yasser Kadhim; [2017]
    Keywords : Micro Fibrillated Cellulose MFC films; MFC Metalization; MFC packaging; PVD thin film coating;

    Abstract : In this thesis, two MFC based films Carboxymethylated-Microfibrillated Cellulose (MFC) and Enzymatic-MFC were characterized and metalized in order to improve the barrier properties at high relative humidity. Several methods were used for the characterization process, which were Atomic Force Microscopy (AFM), Contact Angle (CA), Energy Dispersive Spectra (EDS), Light Microscopy (LM), Scanning Electron Microscopy (SEM), and Oxygen Transmission Rate (OTR).
