✦ Synopsis

Swift heavy ions ISHI), ions with energy which produce large electronic energy loss are now being used for modification of the properties of the materials through electron phonon coupling. Characteristic defects produced by heavy ions in insulators can also be produced in other materials if sufficient energy can be locked into electronic energy which can be transferred to the lattice. Electronic energy loss in the materials can be varied in the range of eV/A to IO keV/A by choosing appropriate ions and their energies. This flexibility coupled with new possibilities with cluster beams are providing opportunities to engineer the properties of all kinds of materials for the future.
