ion implantation
(rus. ионная имплантация otherwise ионное внедрение; ионное легирование)
—
impacting of extrinsic atoms into a solid by bombarding its surface with accelerated ions.
Description
Penetration of ions into the bombarded object (target) occurs during ion bombardment of solids along with the surface sputtering process, ion-ion emission, formation of radiation defects, etc. The most common application of ion implantation is the doping of semiconductors for the production of p-n junctions, heterojunctions, low-resistance contacts. Ion implantation into metals is used in order to increase their hardness, durability, corrosion resistance, etc. Ion bombardment of high-temperature superconductors belonging to the RBa2Cu3Ox family can be used to create highly effective pinning centres and significantly increase the critical current density.
