In the range 100 K-800 K we show that, both, the temperature dependence of the hole concentration and Hall mobility is satisfactorily described using the relaxation time approximation. Performing a detailed comparison of in-situ vs. implantation doping, we evidence an incomplete activation of the dose (about 50 &PLUSMN; 10 %) with apparition of a large number of compensating centres in the implanted layers. %G English %L hal-00543771 %U https://hal.science/hal-00543771 %~ CNRS %~ UNIV-MONTP2 %~ GES %~ UNIV-MONTPELLIER %~ UM1-UM2 %~ TEST3-HALCNRS
