Popis: | Implanted positive muons, used to mimic protons, are observed to form a diamagnetic state in the chalcopyrite semiconductor CuInSe2. A shift of the muon precession frequency is observed at a high transverse magnetic field (1600 G) and is interpreted as being associated to the presence of a transient neutral state. A high charge or spin flip rate of the electron bound to the muon is suggested to be the cause for the absence of a hyperfine splitting, i.e., a direct signature of a neutral state. This observation is consistent with the presence of a hydrogen donor level close to or above the conduction band minimum. |
