    2020-11-25 · Molybdenum (Mo) and tungsten (W) doping in copper vanadate (Cu 3 V 2 O 8) gives important insights into the modulation of carrier mobility and charge separation efficiency. Mo and W atoms have more valence electrons than vanadium(V), providing extra electrons to the host lattice of Cu 3 V 2 O 8 (CVO) resulting in raising the Fermi level wherein impurity energy levels will act as donors.

By varying the grain size between 5 and 50 nanometers, we show that the flow stress and thus the strength exhibit a maximum at a grain size of 10 to 15 nanometers. This maximum is because of a shift in the microscopic deformation mechanism from …

In 99.9% of cases this wire will be made of copper, whose resistivity at 20°C is about 1.73 × 10 –8 Ω m. However, coils often have to operate above room temperature and will be heated by the operating losses in any case.
