摘要
We report on the stability and dynamics of muonium centers in heavily doped p-type and n-type Si crystals. The measurements were conducted and were carried out at the ISIS facility in the United Kingdom. This allows us to detect weak dipolar interactions between the probe and its surrounding host nuclei. The Mu(+) center was successfully observed in the p-type Si:B sample, where its dipolar interaction with the Si-29 neighboring nuclei was detected. The stability, diffusivity and reactivity of this positive diamagnetic center were clearly identified. On the other hand, the neutral Mu(BC)(0) center appear to dominate the dynamics in the n-type Si:As sample due to its very rapid spin exchange rate (10(6) MHz), and thus it conceals the effect due to the Mu(-) center.
