Sažetak
Measurements of the electrical conductivity and the observations of the accompanying changes of structural properties of bismuth films of different thicknesses were carried out at room temperature. The electrical conduction mechanism was correlated with structural changes occuring during growth of the film. For small thickness d < L, where L is the electron mean free path, the film resistance varied as d-n, where n ≈ 2. However, for d > L the value of n become smaller than 2.
