Dislocation structures in diamond: density-functional based modelling and high-resolution electron microscopy
2004 (English)In: Defect and Diffusion Forum, ISSN 1012-0386, Vol. 226-228, 11-30 p.Article in journal (Refereed) PublishedText
The core structures of perfect 60 and edge dislocations in diamond are investigated atomistically in a density-functional based tight-binding approach, and their dissociation is discussed both in terms of structure and energy. Furthermore, high resolution electron microscopy is performed on dislocation cores in high-temperature, high-pressure annealed natural brown diamond, and HRTEM image simulation allows a comparison of theoretically predicted and experimentally observed structures.
