dc.description.abstract | We describe an approach to ion implantation in which the plasma and its electronics are held at
ground potential and the ion beam is injected into a space held at high negative potential, allowing
considerable savings both economically and technologically. We used an “inverted ion implanter”
of this kind to carry out implantation of gold into alumina, with Au ion energy 40 keV and dose
(3–9) × 1016 cm−2. Resistivity was measured in situ as a function of dose and compared with predictions
of a model based on percolation theory, in which electron transport in the composite is
explained by conduction through a random resistor network formed by Au nanoparticles. Excellent
agreement is found between the experimental results and the theory. | |
