Oblique stacking of three-dimensional dome islands in GeÕSi multilayers
The organization of Ge ‘‘dome’’ islands in Ge/Si multilayers has been investigated by cross-sectional transmission electron microscopy. Ge domes are found to spontaneously arrange in oblique stacks, replicating at a well-defined angle from one bilayer to the next. The formation of oblique island stacks is governed by a complex interplay of surface strain, generated by the already buried islands...
متن کاملThe oblique effect and three-dimensional shape.
The classical oblique effect refers to the finding that observers are faster and more accurate in discriminating the orientation of a line or edge when it is at or near vertical or horizontal than when it is at an oblique orientation (Appelle, 1972; Mach, 1861). Based on the finding that observer sensitivity to orientation of simple symmetric shapes like an ellipse or the letter "X" also exhibi...
متن کاملNumerical Study on the Crushing Behavior of Square Tubes Under Three Dimensional Oblique Loading
This study aims to numerically investigate on the crashworthiness of thin-walled square tubes by consideration of 3-D oblique loading. In this type of loading, direction of loading is defined by using two spatial angles relative to the position of the tube. To this aim, finite element (FE) analysis is employed to simulate the loading for 8 different numerical models with different loading orien...
متن کاملThree-dimensional photonic crystals by large-area membrane stacking.
We designed and analyzed a "mesh-stack" three-dimensional photonic crystal of a 12.4% bandgap with a dielectric constant ratio of 12 : 1. The mesh-stack consists of four offset identical square-lattice air-hole patterned membranes in each vertical period that is equal to the in-plane period of the square lattice. This design is fully compatible with the membrane-stacking fabrication method, whi...
