Abstract
The bound state of an isotropic muonium atom has been detected in both n- and p-type InSb using a high-field μSR technique. The hyperfine constant obtained for this center (A=2464±1MHz) is characteristic of deep-level Mu0 centers at tetrahedral interstitial sites in other cubic semiconductors, which typically ionize above 300K. In contrast, the Mu0 center in InSb disappears above about 30K, which is more characteristic of ionization of a shallow-level impurity. The charge-state dynamics of Mu in InSb is discussed in terms of a deep trap or recombination center, rather than as electron ionization.
