  5. 19. Characterization of Bi-incorporated InSb(111)A/B Surfaces : An STM and XPS Study

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

    Author : Shengpeng Huang; [2023]
    Keywords : indium antimonide; surface reconstructions; bismuth deposition; scanning tunneling microscopy; X-ray photoelectron spectroscopy.; Physics and Astronomy;

    Abstract : In recent years, III-V semiconductor materials have received increasing attention due to their admirable electronic properties like direct tunable bandgaps and high charge carrier mobility. Indium Antimonide (InSb) possesses the largest electron mobility among III-V materials and is promising for infrared detectors, high-speed field effect transistors, and spintronics. READ MORE

  6. 20. THE GOTHENBURG COLOURISTS - Analysis of selected works by Karin Parrow, Ivan Ivarsson and Ragnar Sandberg

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Sebastian Karlsson; [2022-11-28]
    Keywords : Gothenburg; colourists; pigment; analysis; Göteborg; Kolorister; Karin Parrow; Ivan Ivarsson; Ragnar Sandberg;

    Abstract : ABSTRACT Paintings from three selected Gothenburg colorists, Karin Parrow, Ivan Ivarsson and Ragnar Sandberg were analysed to gain insight into their use of colour. The Gothenburg colorists refers to a group of artists who were active in the Gothenburg area and west coast of Sweden, most of them had studied under Tor Bjurström (1888-1966) at the Valand Academy of art during the 20s.
