Patterns Formed By Broad Ion Bombardment With Concurrent

The nanoscale patterns that spontaneously form when a material is subjected to bombardment by a broad ion beam have been a subject of great interest for many decades. This technique has the potential to be an extremely powerful and economical way of generating nanoscale structures for a myriad of applications. In this talk I will report recent theoretical results which show that rotating a binary sample during bombardment can change the characteristics of the resultant pattern significantly.
