We present a study of electric instability in GaAs/AlGaAs hetero-structure two-dimensional electron gas system under high magnetic fields. As the applied dc current exceeds a threshold value Ith, the longitudinal voltage Vxx drops, fluctuate

In this thesis, the effect of different donors on the magnetic properties of Co-doped ZnO was investigated, and it was found that when the donor level was shallower, the magnetic of samples was larger. We discussed two kind of donor level: ox
