p-n junction formation by Te+ ion implantation into solution-grown Pb1−xSnxTe

Abstract
The ion implantation of Te+ is used to convert layers of n‐type Pb1−xSnxTe into p type. A Te+ ion concentration of greater than 1×1015 cm−2 and a suitable postanneal produce a p‐type layer about 1 μm thick on the surface of n‐type Pb1−xSnxTe.
