  3. 2. Nanostructured Metal Oxide Semiconductors for Functional Applications

    Författare :Anton Landström; Isabella Concina; Alberto Vomiero; Caterina Soldano; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Experimentell fysik; Experimental Physics;

    Sammanfattning : This thesis is about nanostructured metal oxides, their properties, and some of their applications. Semiconducting metal oxides like TiO2, ZnO,and SnO2 have a wide band gap, which means they absorb UV light andgenerate electron-hole pairs. LÄS MER
