Muonium as a model for interstitial hydrogen in the semiconducting and semimetallic elements

SFJ Cox - Reports on Progress in Physics, 2009 - iopscience.iop.org
Although the interstitial hydrogen atom would seem to be one of the simplest defect centres
in any lattice, its solid state chemistry is in fact unknown in many materials, not least amongst …

Oxide muonics: I. Modelling the electrical activity of hydrogen in semiconducting oxides

SFJ Cox, JS Lord, SP Cottrell, JM Gil… - Journal of Physics …, 2006 - iopscience.iop.org
A shallow-to-deep instability of hydrogen defect centres in narrow-gap oxide
semiconductors is revealed by a study of the electronic structure and electrical activity of …

The first 25 years of semiconductor muonics at ISIS, modelling the electrical activity of hydrogen in inorganic semiconductors and high-κ dielectrics

SFJ Cox, RL Lichti, JS Lord, EA Davis, RC Vilão… - Physica …, 2013 - iopscience.iop.org
Early muonium studies provided the very first atomistic pictures of interstitial hydrogen in
semiconductors. By the time ISIS muons came on line, the main crystallographic sites, and …

Diffusion and trapping of Mu in the III–V nitrides

RL Lichti, YG Celebi, SP Cottrell… - Journal of Physics …, 2004 - iopscience.iop.org
Sites and dynamics obtained for muonium (Mu) defect centres provide a good experimental
model for the behaviour of the equivalent hydrogen impurities. We discuss the dynamic …

Muonium in InSb: Shallow acceptor versus deep trap or recombination center

VG Storchak, DG Eshchenko, JH Brewer… - Physical Review B …, 2006 - APS
The bound state of a muonium atom has been detected in both n-type and p-type InSb using
a high-field μ SR technique. The hyperfine constant obtained for this isotropic center (AT …

RF-μSR in electric fields studies of GaP

DG Eshchenko, VG Storchak, SP Cottrell - Physica B: Condensed Matter, 2009 - Elsevier
We report on combined RF-μSR and electric fields (EF) μSR measurements in semi-
insulating GaP. At low temperature the capture of excess carriers by a neutral muonium …
