A density-matrix-based formalism is presented to extract activation parameters for the reorientational motion of an interstitial B defect in Si, a center created by ion implantation. β-radiation detected nuclear magnetic resonance (β-NMR) data show

Using β-radiation detected nuclear magnetic resonance (β-NMR), we investigated the microscopic behavior of implanted 8 Li in nominally undoped ZnSe crystals. From the temperature-dependent amplitudes of high-resolution NMR spectra we conclude a gra

Spin-polarized, radioactive 12B probe nuclei were implanted in microcrystalline Si with typical grain diameters of ∼10 nm . Using β-radiation detected nuclear magnetic resonance (β-NMR) we observed broad, unstructured spectra at room temperature.

β-active probe nuclei are implanted in nominally undoped ZnSe crystals. β-radiation detected nuclear magnetic resonance (β-NMR) studies are described for two different probe nuclei, 8Li and 12B. This way, the implantation behavior of two “opposi

12B probe nuclei are implanted in amorphous Si and monitored by β-radiation-detected nuclear magnetic resonance (β-NMR). Independently of growth conditions and impurity content, we find the same frequency distribution in a variety of samples. This

Spin polarized 12B nuclei were produced in a 11B(d,p)12B nuclear reaction and recoil implanted into a type Ib diamond sample at doses below 1011 cm−2. β-radiation detected nuclear magnetic resonance spectra were measured directly after implantatio

Recently it was shown that substitutional B impurities in Cu metal diffuse via a direct-exchange mechanism. In this paper a model for this mechanism is proposed. From the temperature dependence of the electric field gradient produced by the B atom at
