Abstract
We describe the imaging of dislocations in crystals that are composed of micron-size colloidal particles. The dislocations form in an fcc crystalline film close to the interface with a template that is used to grow these crystals. We use a simple laser diffraction microscope (LDM) to image the strain field of the dislocations on a medium-range length scale. This setup is inspired by the transmission electron microscopy technique used to image dislocations in atomic crystals. Confocal microscopy allows us to reconstruct the defect topology in the colloidal crystal in three dimensions and on the particle scale. We take advantage of the three-dimensional particle coordinates determined by confocal microscopy to simulate LDM image contrast for specific imaging conditions.
Dedicated to Professor Dr. Knut Urban on the occasion of his 65th birthday
