Nanowire systems have become the focus of intense of experimental and theoretical investigations due to their scientific and technological interest. We have presented the experimental study of the electrical transport and magnetoresistance of an array of Te nanowires. We observed a transition from one dimensional metal behavior at high temperatures to localization at low temperatures in the dependences of the resistance vs. temperature. Besides, the magnitoresistance shows its nonmonotonic behavior vs. magnetic field with oscillations, which could be attributed to the quantum confinement in the nanowires.
