Abstract

With their potential to offer new properties, single crystals containing nanoparticles provide an attractive class of nanocomposite materials. However, to fully profit from these, it is essential that we can characterise their 3D structures, identifying the locations of individual nanoparticles, and the defects present within the host crystals. Using calcite crystals containing quantum dots as a model system, we here use 3D stochastic optical reconstruction microscopy (STORM) to locate the positions of the nanoparticles within the host crystal. The nanoparticles are shown to preferentially associate with dislocations in a manner previously recognised for atomic impurities, rendering these defects visible by STORM. Our images also demonstrate that the types of dislocations formed at the crystal/ substrate interface vary according to the nucleation face, and dislocation loops are observed that have entirely different geometries to classic misfit dislocations. This approach offers a rapid, easily accessed, and non-destructive method for visualising the dislocations present within crystals, and gives insight into the mechanisms by which additives become occluded within crystals.

Atomistic structure of misfit dislocations in SrZrO{sub 3}/SrTiO{sub 3} interfaces

Journal Article Ernst, F. ; Ruehle, M. ; Recnik, A. ; ... - Acta Materialia

The atomistic structure of misfit dislocations at heterointerfaces between two ionic crystals with the perovskite structure, SrZrO{sub 3} and SrTiO{sub 3}, is investigated. The interfaces were fabricated by metal-organic deposition of SrZrO{sub 3} layers on (001) SrTiO{sub 3} single crystal substrates. Under appropriate conditions the SrZrO{sub 3} layer grows epitaxially, with its crystal lattice parallel to the lattice of the substrate (cube-on-cube orientation relationship). In the layer/substrate interface a square network of dislocations accommodates the misfit between corresponding spacings in the two crystals. These misfit dislocations have edge character, <010> line directions, and <100> Burgers vectors parallel to the interface.more »« less

Epitaxial growth of fcc-Co{sub x}Ni{sub 100-x} thin films on MgO(110) single-crystal substrates

Journal Article Ohtake, Mitsuru ; Nukaga, Yuri ; Sato, Yoichi ; ... - Journal of Applied Physics

Co{sub x}Ni{sub 100-x} (x=100, 80, 20, 0 at. %) epitaxial thin films were prepared on MgO(110) single-crystal substrates heated at 300 deg. C by ultrahigh vacuum molecular beam epitaxy. The growth mechanism is discussed based on lattice strain and crystallographic defects. CoNi(110) single-crystal films with a fcc structure are obtained for all compositions. Co{sub x}Ni{sub 100-x} film growth follows the Volmer-Weber mode. X-ray diffraction analysis indicates that the out-of-plane and the in-plane lattice spacings of the Co{sub x}Ni{sub 100-x} films are in agreement within +-0.5% with the values of the respective bulk Co{sub x}Ni{sub 100-x} crystals, suggesting that the strainmore »« less

Visualization of the effect of additives on the nanostructures of individual bio-inspired calcite crystals

Journal Article Ihli, Johannes ; Clark, Jesse N. ; Kanwal, Nasima ; ... - Chemical Science

Soluble additives provide a versatile strategy for controlling crystallization processes, enabling selection of properties including crystal sizes, morphologies, and structures. Here, the additive species can also be incorporated within the crystal lattice, leading for example to enhanced mechanical properties. However, while many techniques are available for analyzing particle shape and structure, it remains challenging to characterize the structural inhomogeneities and defects introduced into individual crystals by these additives, where these govern many important material properties. Here, we exploit Bragg coherent diffraction imaging to visualize the effects of soluble additives on the internal structures of individual crystals on the nanoscale. Investigationmore »« less

Strain-relief by single dislocation loops in calcite crystals grown on self-assembled monolayers

Journal Article Ihli, Johannes ; Clark, Jesse N. ; Côté, Alexander S. ; ... - Nature Communications

Most of our knowledge of dislocation-mediated stress relaxation during epitaxial crystal growth comes from the study of inorganic heterostructures. In this study, we use Bragg coherent diffraction imaging to investigate a contrasting system, the epitaxial growth of calcite (CaCO ₃) crystals on organic self-assembled monolayers, where these are widely used as a model for biomineralization processes. The calcite crystals are imaged to simultaneously visualize the crystal morphology and internal strain fields. Our data reveal that each crystal possesses a single dislocation loop that occupies a common position in every crystal. The loops exhibit entirely different geometries to misfit dislocations generatedmore »« less
