Abstract
Nuclear magnetic resonance (NMR) has been used to probe the atomic displacements and bond bending around an isovalent impurity (In) in the GaAs lattice. It is concluded that the In atoms substitute on the Ga sublattice, that they do not cluster, and that the strain field induced by these isolated atoms is sufficient to affect the NMR of arsenic atoms as far away as 30 Å. Estimates of bond angle distortions in the nearest atomic shells around the In atom are discussed.Keywords
