| Research Abstract |
Use of low energy electron beam (~1 keV) in analytical electron microscopy significantly reduces the surface charge-up of semi-insulating wide bandgap materials and realizes high spatial resolution. We developed SEM-cathodoluminescence (CL) system for 1keV observation and realized CL nanospectroscopy of semi-insulating materials without metal-coating. We also visualized growth direction domains within ZnO nanorod single crystal and observed strain-induced bandgap shrinkage of ZnO.
