On the faceting of ceramic surfaces

Strain in Nanoscale Germanium Hut Clusters on Si(001) Studied by X-Ray Diffraction

“…Scanning probe microscopy techniques have revealed a vast amount of information concerning thin film growth and the shapes and size distributions of such islands [6,[12][13][14]. However, it is difficult to determine the internal atomic structure of the islands, the strain fields, and the interface structure of small islands.…”

High‐Temperature Morphological Evolution of Lithographically Introduced Cavities in Silicon Carbide

“…These observations suggest that the { } 1210 faces are unstable, i.e., not a component of the Wulff shape, and thereby unstable to breakdown into a "hill-and-valley" structure, as originally described by Herring [21]. These observations have a parallel in undoped sapphire, where experimental evidence shows that { } 1210 -type surfaces are stable and develop ledges that increase in height with anneal time, but the orthogonal { } 1010 surfaces break down into a series of inclined facets via a nucleation and growth process [19,[22][23][24].…”

Final technical report on Award No. DE-FG02-92ER45465

“…Herring's theorem states that any surface which is not a part of the Wulff shape (high-index, higher-energy planes) will reconstruct into a hill-and-valley structure comprising the low-energy facets; edge effects are neglected. The reconstruction of high-index surfaces of AIz03 is well known [23,24]. In particular, the faceting of (1010) (the first-order (m) prism plane) of Alz0, has been studied in great detail.…”
