Investigation of the surface electronic structure of bulk ZnGa2O4 (Conference Presentation)

Paper Abstract

We present a combined experimental and theoretical investigation on the surface electronic structure of truly bulk ZnGa2O4, a transparent conducting oxide with an ultra-wide band gap of 4.6 eV. Angle-resolved photoelectron spectroscopy, X-ray photoelectron spectroscopy and low-energy electron diffraction were used to analyze the electronic band structure, band bending and surface reconstruction respectively. In combination with density functional theory, the experimental results will be discussed to provide the very first insights on the surface electronic properties of ZnGa2O4, to motivate future investigations.
