Ion Beam Modification of Biodegradable Polymeric Biomaterials

In the last years biologically stable biomaterials gives their place to biodegradable biomaterials in packaging, agriculture, medicine, and other application areas. For applications in medicine this happens because of the some problems caused by the regeneration ability of the living tissues and toxic effect of stable polymers. By products of biodegradable polymers leaves no residual mass at th...

Self-organized ordering of nanostructures produced by ion-beam sputtering.

We study the self-organized ordering of nanostructures produced by ion-beam sputtering of targets amorphizing under irradiation. By introducing a model akin to models of pattern formation in aeolian sand dunes, we extend consistently the current continuum theory of erosion by IBS. We obtain new nonlinear effects responsible for the in-plane ordering of the structures, whose strength correlates ...

Simulating discrete models of pattern formation by ion beam sputtering.

A class of simple, (2+1)-dimensional, discrete models is reviewed, which allow us to study the evolution of surface patterns on solid substrates during ion beam sputtering (IBS). The models are based on the same assumptions about the erosion process as the existing continuum theories. Several distinct physical mechanisms of surface diffusion are added, which allow us to study the interplay of e...

Focused Ion Beam Microscopy and Micromachining

The FIB Instrument The basic functions of the FIB, namely, imaging and sputtering with an ion beam, require a highly focused beam. A consistent tenet of any focused beam is that the smaller the effective source size, the more current that can be focused to a point. Unlike the broad ion beams generated from plasma sources, high-resolution ion beams are defined by the use of a field ionization so...
