Ion implantation has been successfully used in doping semiconductors such as silicon and gallium arsenide. In particular, applications of ion implanted diamond have recently come to light. In these studies, the electrical conductivity and other physical properties could be controlled by ion-implanting diamond. However, only a few applications for electrochemical uses by preparing conductive electrodes have been reported [16,17]. 

PE foams containing gold particles which can be moulded or machined into shapes are being developed for applications where atomic particle reflectance or absorption is needed. Uses in neutron radiation environments and in ion implantation technology are envisaged. Uses may also develop from the high electrical conductivity of gold. 

The technology involves the application of low-intensity, direct electrical current across electrode pairs that have been implanted on each side of the contaminated soil. The electrical current induces electroosmosis and ion migration between the two implanted electrodes. Depending on their charge, the contaminants accumulate on one of the electrodes and are extracted to a recovery system (Fig. 14.4). Improved performance of electrokinetics could be attained by the introduction of surfactants. 

Application In order to change the physical, chemical, or electrical properties of the solid substrate, ion implantation technique has been widely used in semiconductor device manufacturing and in metal finishing, for example, semiconductor doping, silicon on insulator (SOI) substrates preparation, and steel toughening. 

Many applications currently exist for carbon composite and polymer materials. Ion implantation is a technique that can result in a combination of the best properties of polymers and of carbon composites. Polymers, used for stmctural and packaging applications, have disadvantages, which usually include softness, low thermal stability, high chemical permeability, and low electrical conductivity. The lack of electrical conduction can lead to problems such as triboelectrification and electrostatic charging. The electrical conduction properties of polymers can be controlled by ion implantation. Ion implantation can make any polymer surface electrically conductive, chemically impermeable, and mechanically hard. Some appli-...
