Muonium as a probe of point defects in type-Ib diamond

K. Yokoyama, J. S. Lord, H. Abe +1

Muonium (Mu), a bound state of a positively charged muon and an electron, can diffuse through crystal lattices and interact with defect centers in insulators and semiconductors. We…

Decoupling bulk and surface recombination properties in silicon by depth-dependent carrier lifetime measurements

K. Yokoyama, J. S. Lord, J. Miao +2

Muons, as a bulk probe of materials, have been used to study the depth profile of charge carrier kinetics in Si wafers by scanning the muon implantation depth. The photoexcited muo…
