With this method, a magnetic field generated by powerful permanent magnets of rare-earth (NdFeB: 1.25 T) was applied perpendicularly to the plume generated between the target and substrate. The flying particles and clusters subjected to Lorentz force are thought to be associated with complicated evaporation processes. Using this method, we obtained an ITO film with a resistivity of 7.2×10^<-5> Ω・cm was obtained. However, the film resistivity obtained by this method was not always reproducible. In an attempt to improve the reproducibility, we adopted a target-to-substrate (T-S) distance of 10 mm instead of the 40~80 mm distance used beforehand. Under this new condition, the substrate was instantaneously exposed to the plume at high temperature. Upon receiving the thermal energies within the plume, the crystallization properties of the films improved and the values of carrier concentration increased. Statistically, our method had a 75 % probability of obtaining ITO films with a resistivity on the order of 10^<-5> Ω・cm. In the fabrication of AZO films, a resistivity of 8.54×10^<-5> Ω・cm was obtained by optimizing the applied magnetic field, T-S distance, and other preparation conditions.}, pages = {11--25}, title = {Low Resistivity Transparent Conducting Oxide Thin Films Prepared by Pulsed Laser Deposition}, volume = {115}, year = {2004} }
