Paper Abstract

In the n-type silicon alloyed by phosphorus and compensated by zinc on a background wide and intensive Lorentz lines the narrow undistinguished signal have been discovered. In a narrow interval ol magnetic fields it finds out thin SF1 structure. It is characterize for the ionic pair which are taking placc in triplet condition. The mathematical analysis of spectrum EPR of the second signal specifies formatior of the individual ionic pair formed spin-free by neutral zinc atom and positively charged ion phosphorus (spin S=1/2). From dipole constants follows that the distance between zinc atom and phosphorus in ionic pair makes about 10Å (two nuclear distances of silicon). Temperature dependence of spectrum EPR of this ionic specifies pairs appreciable increase in distance in it at temperatures below 183K that apparently is caused by phase transition in a vicinity of this pair. Spectral parameters of ionic pair Zn-P are determined.
