Slow relaxations of magnetoresistance in AlGaAs-GaAs quantum well structures quenched in a magnetic field
N. V. Agrinskaya, V. I. Kozub, D. V. Shamshur +2
We observed a slow relaxation of magnetoresistance in response to applied magnetic field in selectively doped p-GaAs-AlGaAs structures with partially filled upper Hubbard band. We…
Comment on "Weak localization in GaMnAs: evidence of impurity band transport" by L. P. Rokhinson et. al. (Phys. Rev. B, 76, 161201 R; arXivCond-mat:0707.2416)
N. V. Agrinskaya, V. I. Kozub
We suggest that negative magnetoresistance in small magnetic fields at temperatures lower than 3 K reported in the paper under discussion may be related to superconducting transiti…
Photoluminescence and transport in selectively doped p-GaAs/AlGaAs quantum wells: manifestation of the upper Hubbard band
N. V. Agrinskaya, Yu. L. Ivanov, P. V. Petrov +1
By selective doping (Be) of the well and barrier regions of p-GaAs/AlGaAs structures we have realized the situation where the upper Hubbard band (A+ centers) has been occupied by h…
