    Sammanfattning : The aim of this study is to analyse the factors underlying successful reading and writing education and the educational conditions promoting reflective didactic skills, focusing on the students’ develop­ment of reading and writing abilities. Large international surveys indicate that the consensus concerning read­ing and writing education achieved by science during the past decade has had limit­ed impact on class­room activities. LÄS MER

  3. 2. Structure-dependent charge transfer at the interafce between organic thin films, and metals and metal oxides

    Författare :Sareh Ahmadi; Oscar Tjernberg; Guy Le Lay; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photoelectric spectroscopy; X-ray absorption spectroscopy; organic semiconductors; phthalocyanine; charge transfer; electronic structure; dye sensitization;

    Sammanfattning : The purpose of the research work, presented in this thesis is to offer a detailed atomic level study of interfaces created by adsorption of organic molecules on metals and metal oxides to point out significant impact of substrate, dye structure as well as different mediators on the charge transfer at these interfaces, which is proven to influence the device performance to a great extent.Adsorption of organic photosensitive molecules on metals and metal-oxides is the main focus of this thesis.

  4. 3. Consequences of a non-trivial band-structure topology in solids : Investigations of topological surface and interface states

    Författare :Magnus H. Berntsen; Oscar Tjernberg; Philip Hofmann; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; spin- and angle-resolved photoelectron spectroscopy; time-of-flight analyzer; laser based light source; topological insulator; topological crystalline insulator; thin films; surface state; interface state; Bi2Se3; Pb1-xSnxSe;

    Sammanfattning : The development and characterization of experimental setups for angle-resolved photoelectron spectroscopy (ARPES) and spin- and angle-resolved photoelectron spectroscopy (SARPES) is described. Subsequently, the two techniques are applied to studies of the electronic band structure in topologically non-trivial materials. LÄS MER
