Abstract

Pulsed laser deposition is a technique commonly used to deposit high quality thin films of high temperature superconductors. We discuss the results obtained when this technique is applied to the deposition of Tl-CA-Ba-Cu-O thin films using a frequency doubled Nd:YAG laser operating at 532 nm and an excimer laser operating at 248 nm. Films with onset temperatures of 125 K and zero resistance temperatures of 110 K deposited on (100) oriented MgO from a composite T12Ca2Ba2Cu3Ox target were obtained at both wavelengths upon appropriate post deposition annealing. We will discuss the microstructure and composition as a function of laser wavelength and annealing conditions.
