Non-Stoichiometric Transfer of Complex Oxides by Pulsed Laser Deposition at Low Fluences
Published online by Cambridge University Press: 15 February 2011
Abstract
We provide evidence that non-stoichiometric ablation of YBa2Cu3O7δ at low fluences is due to a phase separation of the target surface. On the other hand, in SrTiO3 we find at low fluences evidence for preferential ablation which is assisted by volume-diffusion. As a result, the Sr/Ti ratio of the ablated films can be tuned by choosing the appropriate fluence.
