How does film thickness impact the resistivity of films?4 answersThe resistivity of films is influenced by their thickness. Thinner films exhibit a drastic increase in conductivity, while thicker films have lower carrier density. The resistivity behavior in these films follows the variable range hopping model, indicating disorder-induced localization of charge carriers. In the case of calcium manganese oxide (CMO) thin films, a remarkable decrease in resistivity is observed with decreasing film thickness, possibly due to oxygen deficiency promoted by tensile strain. For diamond-like carbon (DLC) coatings, an increase in thickness leads to a decrease in electrical resistance, attributed to an increase in the proportion of carbon atoms with sp2-hybridization and the appearance of additional π-bonds. In Nd0.7Sr0.3MnO3 thin films, resistivity increases in the insulating region and is analyzed based on the variable range hopping model.
