Characterization of ZnxMg1−xO:Al thin films deposited by RF sputtering — •Philipp Schurig, Marc Dietrich, Philipp Hering, Angelika Polity, and Bruno K. Meyer — Justus-Liebig-Universität Gießen, 1. Physikalisches Institut, Giessen, Deutschland
ZnxMg1−xO:Al is a transparent conductive oxide-semiconductor (TCO) with a tunable band gap which can be used for example as a photovoltaic electrode material. For this application a wide band gap as well as good conductivity is necessary. The thin films were deposited by RF sputtering on c-sapphire and float glass substrates. A ceramic ZnO target with two weight percent Al2O3 and mounted Mg-stripes was used. The band gap can be controlled through the magnesium content between 3.3 and 7.8 eV. The influences of the magnesium content on structural, optical and electrical properties are investigated using XRD-, SEM-, transmission- and Hall-measurements.
