The stability and dynamics of the positively charged hydrogen pseudo-isotope muonium (Mu ΓΎ ) in heavily doped p-type Si:B was investigated using mSR (muon spin rotation/resonance/relaxation). These measurements were carried out in the absence of an applied field. Under these circumstances, the muon

Muon spin precession in weak transverse magnetic fields and zero-field muon spin depolarization data are used to characterize the Mu ΓΎ states in p-type InAs. A low-temperature signal, assigned to the BC site, shows the onset of motion just above 150 K. Above 250 K, the Mu ΓΎ diffusion proceeds via a
We have studied the low-temperature photoluminescence of high-mobility two-dimensional hole gases in GaAs quantum wells in magnetic ΓΏelds up to 50 T. We have observed both spin states of the neutral (X0) and of the singlet state of the positively charged exciton (X + ), allowing us to determine thei
