  1. 1. Correlating Photoconductivity with Photochromism in Oxygen-containing Rare-earth Metal Hydride Thin Films

    University essay from Uppsala universitet/Materialfysik

    Author : Suraya Kazi; [2021]
    Keywords : Rare-earth metal hydride; Thin film synthesis; Thin film characterization; Optical properties; Electrical properties; Chemical composition; Photochromic materials; Photoconductivity;

    Abstract : Scientists have recently discovered simultaneous photoconductivity and photochromism (i.e., optical switching upon light exposure) of oxygen-containing rare-earth metal hydrides (REMHO). A deep understanding of these extraordinary optical and electrical properties can open the door to advanced technological uses such as smart windows. READ MORE

  3. 2. Synthesis and characterization of novel hybrid organic-inorganic materials

    Abstract : Efterfrågan på bättre och mer hållbart material ökar. Mer effektivt material kommer att behövas för att möta den ökande, globala efterfrågan. READ MORE

  4. 3. Electric Transport of Rare-earth Metal Oxy-hydride Thin Films

    University essay from Uppsala universitet/Materialfysik; Uppsala universitet/Tillämpad kärnfysik

    Author : Suraya Kazi; [2021]
    Keywords : Photochromism; Photoconductivity; Rare-earth Metal Oxy-hydride; Electric Transport; Photodarkening; Yttrium Oxy-hydride;

    Abstract : In this project, I investigate the photoconductivenature of photochromic rare-earth metal oxy hydrides (REMHO). Such materials have received increasingscientific attention since they show a color-neutralphotochromic effect that can be applied, e.g., in smartwindows or chromogenic devices. READ MORE

  5. 4. Photoconductivity in rare earth metal-oxy-hydrides

    University essay from Uppsala universitet/Materialteori

    Author : Félix Treuil-Dussouet; [2020]
    Keywords : Photoconductivity;

    Abstract : In this project the evolution of resistivity under light exposition in materials like rare earth metal-oxy-hydrides is studied. These materials observe a decrease of the resistance when exposed under the light of a 19,5 W power lamp, and slowly tend to return to their initial resistance. READ MORE
