Nanoscale ion implantation using focussed highly charged ions

open access: yesNew Journal of Physics, 2020
We introduce a focussed ion beam (FIB) based ion implanter equipped with an electron beam ion source (EBIS), able to produce highly charged ions. As an example of its utilisation, we demonstrate the direct writing of nitrogen-vacancy centres in diamond ...

Ion implantation and low-temperature epitaxial regrowth of GaAs [PDF]

open access: yes, 1981
Channeling and transmission electron microscopy have been used to investigate the parameters that govern the extent of damage in ion‐implanted GaAs and the crystal quality following capless furnace annealing at low temperature (∼400 °C). The implantation‐

Optical doping and damage formation in AIN by Eu implantation [PDF]

open access: yes, 2010
AlN films grown on sapphire were implanted with 300 keV Eu ions to fluences from 3×1014 to 1.4×1017 atoms/cm2 in two different geometries: “channeled” along the c-axis and “random” with a 10° angle between the ion beam and the surface normal.
