title: Nanoscale mapping of optical band gaps using monochromated electron energy loss spectroscopy.
abstract: 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.
