Change in the Lattice Configuration of Nanothin Space-Dissipative Structures Formed in an Amorphous Film

Phenomenon of relaxation of inhomogeneous elastic rotational curvature of the lattice of nanofine spatial dissipative structures of hexagonal selenium

“…The bending contours deviate from the direction of the lowest formation speed towards the direction of the highest formation speed of NRSDS occur when moving take place along the direction of the lowest formation rate of NRSDS, which coincides with the short diagonal of a rhombus (Figure 1 It has been established that the lattice of NRSDS of hexagonal selenium (Figure 1 a) experiences an inhomogeneous elastic rotational curvature of the lattice around two mutually perpendicular directions around [001], which coincides with the OZ axis (Figure 2) and around the direction of OX (Figure 2), which coincides with the long diagonal of the rhombus [15][16][17][18]. Calculations performed using standard crystallographic formulas show that the rotation of the lattice in the reference plane (001) reaches 18°, and the deviation of [001] from a position parallel to the plane of the film reaches 22°.The features of the patterns of bending extinction contours on the electron microscopic images of NRSDS indicates that the rotational curvature of the lattice of NRSDS with a linear fan-shaped system of bending contours has continuous progressive nature.…”

“…It is clear that this nature of the change in the intercontour distances is due to an increase in the bend radius of the lattice of NRSDS in the direction of the opening of the 'fan' of the contours. Given the straightforwardness and continuity of bending contours present on the electron microscopic images of NRSDS and formulas (3) [17], it is clear that the increase in the radius of the rotational curvature of the lattice will occur according to a linear law. The calculations performed using the formulas of the bending contour method [19,20] and formula (3) confirm the above conclusion.…”

“…It is known that the formation of interblock boundaries take place with varying module of the misorientation vector  in NRSDS of hexagonal seleniumnanofine crystals after the stage of quenching of NRSDS's [1][2][3][4]. This phenomenon is the result of relaxation of an inhomogeneous elastic rotational curvature of the lattice around [001] in one of NRSDS block [5][6][7][8][9].…”
