Abstract As a one-atom thick, mechanically strong, and chemically stable material with unique electronic properties, graphene can serve as the basis for large number of applications. One way to tailor its properties is controlled introduction covalently bound heteroatoms into lattice. In this study, we demonstrate efficient implantation individual gold atoms up concentration 1.7 × 10 11 cm −2 v...

AbstractThe optics of any camera degrades the sharpness photographs, which is a key visual quality criterion. This degradation characterized by point-spread function (PSF), depends on wavelengths light and variable across imaging field. In this paper, we propose two-step scheme to correct optical aberrations in single raw or JPEG image,i.e., without prior information lens. First, estimate local...
