Detection of hydrogen in nominally pure GaP:Zn by optically detected electron nuclear double resonance

Optically detected electron nuclear double resonance (ODENDOR) measurements of the triplet antisite center P Ga 3+ in GaP:Zn have revealed the presence of hydrogen atom impurities in a nominally pure sample. Strong ligand 31P signals have also been observed. Assuming a uniform distribution of hydrog...

Description
Summary:Optically detected electron nuclear double resonance (ODENDOR) measurements of the triplet antisite center P Ga 3+ in GaP:Zn have revealed the presence of hydrogen atom impurities in a nominally pure sample. Strong ligand 31P signals have also been observed. Assuming a uniform distribution of hydrogen the intensity ratio of the 31P to 1H lines sets a rough lower limit of between 1–10 ppm on the hydrogen concentration. The possibility that the H 1 atoms form part of the antisite defects is also discussed.
