  1. 1. Heteroepitaxial Growth of GaN Film on Si substrate by Magnetron Sputtering

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

    Author : Zahra Mohammadianrasnani; [2023]
    Keywords : GaN; Sputter epitaxy; Thin film;

    Abstract : In this study, the effect of AlN buffer layer structure and morphology on the GaN films deposited on Si (111) substrate by reactive DC magnetron sputtering have been studied. For structural and morphological characterization X-ray diffraction (XRD) and Scanning electron microscope (SEM) were used. READ MORE

  3. 2. Magnetron Sputter Epitaxy of High-quality GaNand Plasma Characterization of the Process : Degree Project–Master’s Thesis

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Yi-Ling Lo; [2021]
    Keywords : GaN; Semiconductors; Nanomaterials; Thin film; Magnetron Sputtering; Epitaxy; XRD; Physical Vapor Deposition;

    Abstract : Several sputtering depositions were done by direct current (DC) magnetron sputtering epitaxy (MSE) techniquefor the goal of improving the growth rate and crystalline quality of GaN thin film on Al2O3 substrate. Thegrowth rate was higher when substrate-to-target distance D = 7 cm compared with D = 9. READ MORE

  4. 3. Investigation of magnetic order in nickel-5d transition metal systems

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Konstantinos Papadopoulos; [2019]
    Keywords : muSR; muons; skyrmions; magnetism; transition; spin; rotation; relaxation; resonance; thin; films; transition; metals; MBE; sputtering; XRR; reflectivity; molecular; beam; epitaxy; x; ray; TRIUMF; double; perovskite; longitudinal; transverse; nickel; Ni; asymmetry; positron; depolarization; chiral; lattice; helical; DM; interaction;

    Abstract : Double perovskite materials exhibit alterations in magnetic order through manipulation oftheir crystal structure. Certain ultra thin metallic bilayers can create an exotic magnetic stateof confined spin textures called skyrmions. In both cases, new atomic arrangements leadto new electrical and magnetic properties. READ MORE
