摘要: Results on the absorption and electron paramagnetic resonance measurements chromium-doped GaAs are reported. For $p$-type samples main optical transitions shown to be due a photoionization process which has been measured as function of temperature hydrostatic pressure. A model, developed in configurational diagram scheme using two types relaxation, is proposed explain experimental results.
