Scanning and transmission electron microscopies were used to evaluate the external microstructures and the distribution of dislocations, respectively. The dislocation densities in the PE grown films were reduced at least five orders of magnitude relative to the initial GaN seed layers. Tilting to 0.2° in the portion of the coalesced GaN epilayers grown over the silicon nitride masks was observed via X-ray diffraction. Neither tilting nor low angle boundaries were observed within areas of coalescence in the material grown on substrates without the masks.}, number={2}, journal={INTERNATIONAL JOURNAL OF MATERIALS RESEARCH}, author={Davis, Robert F. and Gehrke, Thomas and Linthicum, Kevin J. and Zheleva, Tsvetanka S. and Rajagopal, Pradeep and Zorman, Chris A. and Mehregany, Mehran}, year={2021}, month={Dec}, pages={163–166} }
