摘要: We present a statistical analysis of the mechanical and transport properties stretched Al nanowires. A molecular dynamics density functional theory is used in combination with annealing techniques to analyze large amount stretching processes new realistic geometries. From these calculations, we generate conductance histogram that compared experimental evidence. New particular geometries appear frequently, correlation between structures peaks can be fairly established. In particular, at first stages nanowire elongation, find configuration Al–Al bonds oriented along direction related peak appearing 3 G 0 histogram. Besides, an dimer found most cases neck last stage stretching, just before breaking point; this reflected 1 0.
