EPR of the lithium ion-dangling bond complex in germanium containing dislocations

We have observed a new EPR spectrum in a lithium-diffused germanium crystal N_D-N_A ≈ 10¹³ cm^-3) containing dislocations. The principal g values are 1.917 ± 0.002, 1.896 ± 0.002, and 0.855 ± 0.010 along the axes <1$\text{1}$0>, <11$\text{2}$>, and <111>, plus equivalent sets. As this new spectrum is seen in lieu of the dislocation dangling bond spectrum, we attribute it to a lithium ion- dislocation dangling bond complex.
