    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.

    Copper loss is the term used to describe the energy dissipated by resistance in the wire used to wind a coil. 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.
