Three-dimensional geometry of nanometer-scale AlN pits: A new template for quantum dots?
The exact 3D geometry of nanometer-scale AIN pits is determined by Z-contrast imaging. The figure shows the 3D geometry of an AIN nano-pit and its corresponding GaN quantum dot. An atomic-resolution Z-contrast image is displayed in false color to clearly show the Z-contrast of the image, while the other panel displays a schematic 3D view.
