  5. 3. Defects in Bismuth Vanadate: Insights from First Principles

    Author : Nicklas Österbacka; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; defects; oxides; semiconductors; density functional theory;

    Abstract : Photoelectrochemical water splitting is an attractive technique for sustainable hydrogen production, but its efficiency is heavily dependent on the properties of the semiconducting photoelectrodes used in the process. These properties are intimately connected to the presence of point defects in the materials, and understanding this relationship is a key step towards the development of better photoabsorbers.
