Neutron transmutation doping of high-purity InP

Abstract
Transmutation doping of high‐purity n‐type InP has been used to identify the photothermal ionization photoconductivity peaks due to Sn donors. The results obtained show that Sn and S donors in InP have the same ionization energy and the same ground‐state central cell shifts within a resolution of 0.006 meV.
