The surface morphology of film material directly affects its physical performance. It is of greatsignificance for finding out its prospective physical performance to characterize the surface morphologyof film material. It is hard to characterize them with some conventional methods. The surface morphologyof film material was described from the fractal point of view, and the dimension was correlated with theresistivity of material. The [100]-orientated diamond film was primarily investigated. The results showthat the greater the crystal grain is, the more uniform and regular the orientation is; and the more compactthe arrangement is, the greater the fractal box dimension is. Moreover, when fractal box dimensions werewithin a certain range approximately from 2.92 to 2.97, it presents positively correlative relation with thelogarithm of resistivity, Log(ρ), which resembles the Logistic curve. However, when the other dimensionsare beyond the range mentioned above, resistivity doesn’t change with the increase in dimensions offractal. This study will conduce to illustrating the relationship between the structure of crystal exemplifiedby arrangement and physical performance as well as material preparation
