Formation of a Warped Nanomodular Surface Under Ion Bombardment. A Nanoscale Model of Surface Erosion

A nanoscale model of surface erosion, simulating the process of surface shaping under ion bombardment is considered. The possibility of a ripple topography is demonstrated by means of bifurcations theory methods for dynamical systems with an infinite dimensional space of initial data. In particular, we use the normal form of Poincare–Dulak.
