Coincident-site lattice matching during van der Waals epitaxy
Van der Waals (vdW) epitaxy is an attractive method for the fabrication of vdW heterostructures. Here Sb2Te3 films grown on three different kind of graphene substrates (monolayer epitaxial graphene, quasi freestanding bilayer graphene and the SiC (6√3 × 6√3)R30° buffer layer) are used to study the vdW epitaxy between two 2-dimensionally (2D) bonded materials. It is shown that the Sb2Te3 /graphe...
متن کاملDistribution of Grain Boundary Planes at Coincident Site Lattice Misorientations
The grain boundary plane distributions in MgO, SrTiO3, MgAl2O4, and Al are compared at lattice misorientations with a coincident site density of greater than or equal to 1/9. In most situations, the most frequently adopted grain boundary orientation is a habit plane of low index and low surface energy that depends on the particular material. Cases where the most common boundary orientation is a...
متن کاملMotion Estimation and Figure-Ground Segmentation Using Log-Polar Images
A motion estimation algorithm for log-polar images, based on a previous general framework [2], is presented. The advantages and disadvantages brought by the use of this kind of foveal imaging are discussed. Within this context, a simple, but quite effective approach for figure-ground segmentation is also proposed. Performance results concerning motion estimation and target segmentation are repo...
متن کاملDesigning the Lattice for Log-Polar Images
Log-polar images have been being used for pattern recognition and active vision tasks for some years. These images are obtained either from true retina-like sensors or from conventional cartesian images by software conversion. From the hardware perspective, the design of such log-polar retinae faces its own technological limitations. In the case of software remappers, however, their very flexib...
متن کاملMobility of an electron in a multimode polar lattice
The interaction of a free electron with a polar lattice possessing more than one infrared-active opticalphonon mode is considered. From the full Lagrangian describing the electron-lattice system in the presence of an applied field we derive an effective electron-phonon coupling constant and an effective longitudinal opticalphonon frequency that we argue give accurate predictions when used in th...
