Spatially Inhomogeneous Solutions for a Modified Kuramoto–Sivashinsky Equation

We study the periodic boundary value problem for a modified Kuramoto–Sivashinsky equation which can serve as a mathematical model describing formation of nanorelief on the surface of a planar target under the action of ion flux. We show that, as in the case of the traditional Kuramoto–Sivashinsky equation, it is possible to obtain spatially inhomogeneous solutions under the condition that the homogeneous equilibrium states can change the stability. We consider local bifurcations. We find sufficient conditions for the existence of shortwave solutions. Bibliography: 11 titles.

Laser-induced dislocations and the formation of nanorelief in the unirradiated region of metallic targets

This paper presents an experimental investigation of the shape and number of defects as well as of the luminescence intensity of the back surface of molybdenum when the front side of the sample is irradiated with laser pulses. It is shown that, in agreement with the dislocation model of the luminescence, there is a correlation between the luminescence intensity and the number of defects formed during irradiation. © 2004 Optical Society of America
