The Mechanism of Interblock-Boundary Formation and the Effect of Disorientation-Vector Sign Variation along Torn Interblock Boundaries in Nanothin Spatial Dissipative Structures

Resumo

By analyzing the patterns of flexural extinction contours present on the electron-microscopic images of nanothin (~80 nm) spatial dissipative structures (SDSs) of hexagonal selenium, i.e., nanothin crystals with elastic rotational curvature of the lattice around [001], the processes of formation of torn interblock boundaries in these structures are investigated. The effect of changing the disorientation-vector sign along the torn interblock torsion boundaries is observed. A model of formation of interblock torsion boundaries is developed for nanothin selenium SDSs, the lattice of which undergoes an elastic rotational curvature around [001].
