- 1. Phys. Rev. B 74, 161201 (2006) , “Detection of magnetic resonance of donor-bound electrons in GaAs by Kerr rotation”, T. A. Kennedy, J. Whitaker, A. Shabaev, A. S. Bracker, and D. GammonMagnetic resonance of electrons in lightly doped GaAs layers has been detected at 5.8 T by magneto-optical Kerr rotation. A study over a wide range of microwave powers shows (1) resonance without dynamic nuclear polarization (DNP), (2) resonance enhanced by DNP, and (3) DNP pinning of the resonance... (Read more)
- 2. Phys. Rev. B 73, 125204 (2006) , “Optically detected magnetic resonance studies of point defects in Ga(Al)NAs”, I. P. Vorona, T.Mchedlidze, D. Dagnelund, I. A. Buyanova, W. M. Chen, K. KöhlerAn optically detected magnetic resonance (ODMR) study of Ga(Al)NAs alloys grown by molecular beam epitaxy on GaAs substrates is presented. A number of grown-in defects were observed which act as nonradiative recombination centers. A detailed analysis of experimental data using a spin Hamiltonian... (Read more)
- 3. Physica B 308-310, 753-756 (2001) , “On the problem of the EL2 structure in semi-insulating GaAs: high-frequency ODEPR/ODENDOR measurements in W-band”, I. Tkach, K. Krambrock and J. -M. SpaethFor almost two decades the structure model of the EL2 defect in semi-insulating (SI) GaAs has been controversially discussed. Neither the isolated AsGa with Td symmetry, nor the AsGa–Asi pair model nor any other AsGa-related defect model could be unambiguously established. The reason was that... (Read more)
