Muonium diffusion dynamics in mercury oxide
Piroto Duarte, J.; Gil, J. M.; Alberto, H. V.; Vilão, R. C.; Weidinger, A.; Ayres de Campos, N.; Cox, S. F. J.; Lord, J. S.; Cottrell, S. P.The diffusion dynamics of the neutral muonium state found in HgO is addressed in this work. We propose a hopping model for the diffusion, and use it to analyse time-domain [mu]SR data. It is found that the diffusion is an incoherent quantum process, with an activation energy of 5.2(2) meV. The analysis also points to the anti-bonding site as the best-suited candidate for the muon's localisation. ; http://www...
Muoniated radicals in the organic semiconductor zinc-phthalocyanine
Duarte, J. Piroto; Vilão, R. C.; Gil, J. M.; Alberto, H. V.; Ayres de Campos, N.; Weidinger, A.[mu]SR experiments were conducted on the organic semiconductor zinc-phthalocyanine (Zn-Pc) in order to identify and characterize the muon states in this material. Transverse-field experiments at 0.5 mT reveal the existence of paramagnetic muon states in Zn-Pc, with the formation probability of nearly 100%. Two different muoniated radicals were detected, with hyperfine parameters of 127 and 142 MHz; muonium is t...
Probing the shallow-donor muonium wave function in ZnO and CdS via transferred ...
Lord, J. S.; Cottrell, S. P.; King, P. J. C.; Alberto, H. V.; Ayres de Campos, N.; Gil, J. M.; Duarte, J. Piroto; Vilão, R. C.; Lichti, R. L.The assignment of muon spin rotation spectra to muonium counterparts of hydrogen shallow-donor states is reviewed in four II-VI widegap semiconductors, CdS, CdSe, CdTe and ZnO. The existence of extended electronic orbitals is argued from the muon-electron hyperfine parameters and supported by the new muon spin repolarization data for CdS and ZnO, characterizing the superhyperfine parameters on the sparse Cd and...
