## Description

- description: 'The local electronic structure of muons (Mu) as dilute pseudo-hydrogen
    in single-crystalline b -Ga2O3 has been studied by the muon spin rotation/relaxation
    (mSR). High-precision measurements over a long time range of 25 ms have clearly
    identified two distinct Mu states: a quasi-static Mu (Mu1) and fast-moving Mu
    (Mu2). By comparing this result with predictions from the recently established
    ambipolarity model, these two states are respectively attributed to the relaxed-excited
    states associated with the donor (E+=0) and acceptor (E-=0) levels predicted by
    density functional theory (DFT) calculations for the interstitial H. Furthermore,
    the local electronic structure of Mu1 is found to be an OMu-bonded state with
    three-coordinated oxygen. The structure is almost identical with the thermal equilibrium
    state of H, and it is found to function as an electron donor. The other Mu2 is
    considered to be in the hydride state (Mu-) from the ambipolarity model, suggesting
    that it is in fast diffusion motion through the short-lived neutral state due
    to the charge exchange reaction with conductionelectrons (Mu0+e- ⇄Mu-).'
