Abstract

The physics of the in-situ laser deposition process is reviewed. Emphasis will be placed on the use of excimer lasers, and the deposition of Y-Ba-Cu-O thin films. It is shown that the laser target interaction conditions, and the properties of the laser generated plume are inducive to the formation of high quality films. In addition to the formation of energetic atomic beams, laser deposition is also highly compatible with reactive deposition which make it suitable for oxide and nitride films. An in-situ diagnostic technique is introduced which is capable of detecting the interfacial boundary layer between the film and the substrate. It is also shown that post-deposition in-situ oxidation is necessary for the formation of superconducting films..
