A report published by researchers at the National Renewable Energy Laboratory (NREL), Yale University, and the Colorado School of Mines offers a new explanation of a tricky phenomenon—dislocations in coalescing crystalline materials—that was selected for a special highlight by the journal APL Materials.   The paper, titled “Perspective: Fundamentals of Coalescence-Related Dislocations, Applied to Selective-Area Growth and Other Epitaxial Films,” was published in APL Materials. Because of the p...
