Nanothin Spatial Dissipative Structures with Rotational Curving of the Grid around Three Mutually Perpendicular Directions

摘要

Nanothin spatial dissipative structures (SDSs) produced by thermal gradient processing of an amorphous selenium film by means of one-sided heating of its lower surface at T= 413 K have been studied by transmission electron microscopy and microdiffraction. It has been established that the resulting nanothin SDSs of hexagonal selenium possess a specific curved habit and a nonlinear fan-shaped system of bending contours in their electron-microscopic image; the lattice of nanothin SDSs undergoes elastic-plastic rotational curvature around three mutually perpendicular directions; the lattice rotation angles of nanothin SDSs of hexagonal selenium reach 25° around [001], 32° around the direction perpendicular to [001] and lying in the plane of the amorphous film, and 35° around the direction perpendicular to the first two directions and not lying in the plane of the amorphous film.
