This paper has studied the electronic properties of multi-diluted magnetic semiconductor (DMS) layers Ga(1 − x)MnxAs interposed between nonmagnetic GaAs layers. The asymmetry confining potential on transmission coefficient by tuning temperature and size was discussed. diluted behave as barriers for spin-up holes quantum wells spin-down holes. Furthermore, we have addressed impact an applied bia...

The Impact of Co and Gd on the structural, magnetic dielectric properties ZnO nanotubes synthesized by co-precipitation is reported. results demonstrate that incorporating into diminished crystallinity while retaining optimum orientation. outcomes transmission electron microscopy scanning examined dopants had no effect morphology produced nanotubes. It was also discovered as frequency concentra...
