Abstract

Deep-level transient spectroscopy (DLTS) was used to characterize native defects of Ga_1-xMn_x layers with x≈2.2% and x≈4.4% grown by molecular beam epitaxy (MBE). Three hole traps at about 0.38±0.01, 0.43±0.01, and 0.65±0.01 eV above the valence band maxima were observed. These traps were found to be associated with the gallium vacancy or the arsenic antisite complex, and single- and double-donor states of arsenic antisite.
