Glückler, R. Khasanov, H. Luetkens, and A. SuterThe formation of hydrogenlike muonium (Mu) has been studied as a function of implantation energy in intrinsic Si, thin films of condensed van der Waals gases (N2, Ne, Ar, Xe), fused and crystalline quartz, and sapphire. By varying the initial energy of positive muons... (Read more)

WellerTo determine if the only source of optical absorption between 5.8 and 5.9 eV is the E center (absorbing at 5.85 eV) two separate suites of type III silica samples were implanted, one with Si and one with O. Several ion energies were used for implantation to produce layers 600 and... (Read more)

Ono, R. Suzuki, T. Ohdaira, T. Mikado.The depth distributions of oxygen-related defects in separation-by-implanted oxygen wafers were determined from measurements of Doppler broadening spectra of the annihilation radiation. Vacanyoxygen complexes were introduced by implanting 180-keV oxygen at (26)×1017 ... (Read more)

Merrill, R. Bleiler.It is important to understand the distribution of recoil-implanted atoms and the impact on device performance when ion implantation is performed at a high dose through surface materials into single crystalline silicon. For example, in ultralarge scale integration impurity ions are often implanted... (Read more)

KawazoeFour sets of ESR doublets with splittings of 9, 23, 26 or 44 mT were observed in dry a-SiO2 (Type IV, OH concentrations1017 cm−3) implanted with 29Si+ to a fluence of 6×1016 cm−2 at 160 keV. These doublets were attributed to the hyperfine structures due to a 29Si nucleus of... (Read more)
