*3.5. Electric Property*

The sheet resistance (Rs) is shown in Figure 6 with various thicknesses and temperature conditions. The result of the present study suggests that the sheet resistance is decreased with the increase of thickness and annealed temperatures. The sheet resistance of the as-deposited and thinner CoFeW films is larger than that of the annealed and thicker CoFeW films because the as-deposited and thinner CoFeW films reduce the electron mobility through the films and enhance the scattering of electrons at grain boundaries and impurities, which shows the same behavior as CdS and CoFe films [35,36].
