A Study of Extended Defects in Surface Damaged Crystals
We have analyzed by transmission electron microscopy silicon and GaAs crystals polished with sandpapers of different grain size. The surface damage induced a crystal permanent convex curvature with a radius of the order of a few meters. The curvature is due to a compressive strain generated in the damaged zone of the sample. Contrary to what was reported in the literature, the only defects dete...
متن کاملSurface states in photonic crystals
The propagation of surface electromagnetic waves along photonic crystal (PC) boundaries is examined. It is shown that in a number of cases, these are backward waves. The nature of surface electromagnetic states localized at the PC boundary is discussed; these states transfer no energy along the boundary (their tangential wave number is zero). An analogy with the well-known Tamm and Shockley sur...
متن کاملStrain engineering in semiconducting two-dimensional crystals.
One of the fascinating properties of the new families of two-dimensional crystals is their high stretchability and the possibility to use external strain to manipulate, in a controlled manner, their optical and electronic properties. Strain engineering, understood as the field that study how the physical properties of materials can be tuned by controlling the elastic strain fields applied to it...
متن کاملStrain Localization in Ductile Single Crystals?
THIS PAPER is concerned with an analysis of strain localization in ductile crystals deforming by single slip. The plastic flow is modelled as rate-insensitive, and localization, viewed as a bifurcation from a homogeneous deformation mode to one which is concentrated in a narrow ‘shear band’, is found to be. possible only when the plastic hardening modulus for the slip system has fallen to a cer...
