Role of the transition state in muon implantation

RC Vilão, RBL Vieira, HV Alberto, JM Gil, A Weidinger - Physical Review B, 2017 - APS
In muon-spin-rotation experiments, positive muons are implanted in the material and come
to rest in the unrelaxed host lattice. The formation of the final configuration requires a lattice …

Photoexcited muon spin spectroscopy: A new method for measuring excess carrier lifetime in bulk silicon

K Yokoyama, JS Lord, J Miao, P Murahari, AJ Drew - Physical Review Letters, 2017 - APS
We have measured excess carrier lifetime in silicon using photoexcited muon spin
spectroscopy. Positive muons implanted deep in a wafer can interact with the optically …

Direct Observation of Hole Carrier-Density Profiles and Their Light-Induced Manipulation at the Surface of

Barrier model in muon implantation and application to

RC Vilão, RBL Vieira, HV Alberto, JM Gil, A Weidinger… - Physical Review B, 2018 - APS
In implantation experiments, the implanted particle is shot with a certain energy into the
material and comes to rest at a site which may not correspond to the final position. The …

Sapphire puzzle: Joint and density functional theory study

RC Vilao, AG Marinopoulos, HV Alberto, JM Gil… - Physical Review B, 2021 - APS
Sapphire (α-Al 2 O 3) has been investigated by the muon spin rotation (μ SR) method in
several experiments in the past. The main μ SR component is a diamagnetic-like signal with …

Muonium defect levels in Czochralski-grown silicon-germanium alloys

We report Muonium (Mu) donor and acceptor levels in Czochralski-grown Silicon
Germanium alloys (Cz-Si 1− x Ge x). Measurement of these defect energies provides an …

Reply to “Comment on 'Role of the transition state in muon implantation'and 'Thermal spike in muon implantation”'

RC Vilão, HV Alberto, RBL Vieira, JM Gil, A Weidinger - Physical Review B, 2020 - APS
The transition state model proposed for muonium formation in solids is critically discussed
with respect to the delayed capture model. The two models differ mainly in how the electron …
