Spatial structure of Mn-Mn acceptor pairs in GaAs.
The local density of states of Mn-Mn pairs in GaAs is mapped with cross-sectional scanning tunneling microscopy and compared with theoretical calculations based on envelope-function and tight-binding models. These measurements and calculations show that the crosslike shape of the Mn-acceptor wave function in GaAs persists even at very short Mn-Mn spatial separations. The resilience of the Mn-ac...
متن کاملInteraction of Mn with GaAs and InSb
The deposition of Mn on to reconstructed InSb and GaAs surfaces, without coincident As or Sb flux, has been studied by reflection high energy electron diffraction, atomic force microscopy and scanning tunnelling microscopy. On both Gaand As-terminated GaAs(0 0 1), (2× n) Mn-induced reconstruction domains arise with n = 2 for the most well ordered reconstructions. On the Ga-terminated (4× 6), th...
متن کاملMixed valency in polynuclear Mn/Mn, Mn/Mn and Mn/Mn/Mn clusters: a foundation for high-spin molecules and single-molecule magnets
Mixed-valent Mn/O dinuclear and polynuclear molecular compounds containing Mn are almost without exception trapped valence. Large differences between the strengths of the exchange interactions within MnMn, MnMn and MnMn pairs lead to situations where MnMn interactions, the strongest of the three mentioned and antiferromagnetic in nature, dominate the intramolecular spin alignments in trinuclear...
متن کاملMeasured lifetimes of metastable levels of Mn X , Mn XI , Mn XII , and Mn XIII ions
An ion storage technique, based on the capture of metastable multiply charged ions from an external ion source into a Kingdon ion trap, has been used to measure the lifetimes of eight metastable levels of Mn ions with 3s3p configurations, k51 – 4. Although several lifetime calculations exist, some of the transition wavelengths have not been previously observed in any source. The lifetimes range...
متن کاملSuppression of electron spin relaxation in Mn-doped GaAs.
We report a surprisingly long spin relaxation time of electrons in Mn-doped p-GaAs. The spin relaxation time scales with the optical pumping and increases from 12 ns in the dark to 160 ns upon saturation. This behavior is associated with the difference in spin relaxation rates of electrons precessing in the fluctuating fields of ionized or neutral Mn acceptors, respectively. For the latter, the...
