Location of the H[+/-] level: Experimental limits for muonium
Lichti, R. L.; Chow, K. H.; Gil, J. M.; Stripe, D. L.; Vilão, R. C.; Cox, S. F. J.The defect energy levels for muonium, a light pseudo-isotope of hydrogen, are investigated to define the equivalent of the H[+/-] level which is predicted to be fixed at a universal energy. Existing results for Mu at donor and acceptor sites in silicon tentatively place Mu[+/-] approximately 0.5 eV above the predicted hydrogen level. Measured donor ionization energies in other materials in which two neutral Mu ...
Oxide muonics: A new compendium
Cox, S. F. J.; Lord, J. S.; Cottrell, S. P.; Gil, J. M.; Alberto, H. V.; Piroto Duarte, J.; Vilão, R. C.; Keeble, D. J.; Davis, E. A.; Keren, A.A new survey of muonium states brings the total of binary non-magnetic oxides studied to 30, with normal muonium--the interstitially trapped atomic state--found in 15 of these. The number of shallow-donor states of the type known in ZnO now also totals 15, but there are hints of several others. Tantalizingly, the shallow-donor and deep-atomic states are found to coexist in several of the candidate high-permitti...
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...
