Department of Physics, Centre for Materials Science and Nanotechnology, University of Oslo, PO Box 1048-Blindern, NO-0316 Oslo, Norway.

Published: March 2017

Using monochromated electron energy loss spectroscopy in a probe-corrected scanning transmission electron microscope we demonstrate band gap mapping in ZnO/ZnCdO thin films with a spatial resolution below 10 nm and spectral precision of 20 meV.
