Neutron transmutation doping of gallium phosphide

Abstract
The doping of GaP with Ge using nuclear transmutation is reported. Electrical and optical measurements were used to characterize the neutron‐irradiated samples. After annealing at 800 °C for 2 h, essentially all the Ge atoms are located on lattice sites where they act as single donors. This is most likely the Ga site. Higher temperatures are needed to anneal all the defects induced during irradiation and decay of the activated nuclei.
