Laser-ablation deposition of uniform thin films of Bi2Sr2CaCu2Ox
TL;DR: In this paper, a rotational technique was used to prepare uniform thin film superconductors by laser ablation, which produces homogeneous films over an area of several square centimeters, and applied the technique to the preparation of (2212) BiSrCaCuO thin films.

Formation of (ca1-xsrx)2pbo4 in bi(pb)-sr-ca-cu-o system - correlation with the formation of the 2223 high-tc phase
TL;DR: In this article, X-ray diffraction data of Bi1.6O10+x samples show a sharp change near the annealing temperature of 845°C. Below this temperature, a solid solution of (Ca0.867Sr0.4Pb0.6Sr2Ca2Cu3.133)2PbO4 is formed and prolonged annaling leads to transformation of the 2212 phase to 2223 phase.

Pulsed Laser Deposition of High Quality ZnO Thin Films
TL;DR: In this paper, the effects of the oxygen partial pressure, substrate temperature and laser wavelength on the structural and optical properties of the films have been studied and the KrF excimer laser (at 248 nm) was found to produce better quality thin films than the frequency doubled Nd:YAG laser (532 nm).

Thin film superconductors grown by laser ablation of PbO and BiPbSrCaCuO
TL;DR: In this paper, the growth of thin films of Pb-doped BiSrCaCuO by laser ablation is described, and they use the ablation technique to ablate multilayers of both doped BiPbSrCACuO and PbO and find a mixture of both 2223 and 2212 phases in the films, exhibiting Tonset of 110K and Tzero of 81K.

In-situ and multilayer laser ablation deposition of Pb2Sr2Y0.5Ca0.5Cu3O8+δ thin films
TL;DR: In this article, thin films of superconducting Pb2Sr2Y0.5Ca 0.5Cu3O8+δ have been grown in situ on (100) MgO substrates using the laser ablation technique, in vacuum, and also in low oxidizing atmosphere.
