Claim 7:
8. An ion implanter, comprising:
an ion source, configured to generate a metal ion beam comprising a plurality of metal ions, the ion source comprising:
an ion chamber to generate an ion beam comprising a metal ion species; and
a charge source, coupled to deliver a metal vapor to the ion chamber, the charge source comprising a charge mixture, the charge mixture comprising:
a first portion, comprising an elemental metal; and
a second portion, comprising a heterogeneous metal fluoride compound formed from a heterogeneous metallic element, different from the elemental metal; and
