Epitaxial ceria films

Another method for production of ceria films is by oxygen-plasma-assisted molecular beam epitaxy (OPA-MBE). This method has been reviewed by Chambers.The advantage of the oxygen assisted plasma technique is that for certain films the dissociation of O2 is limiting in the growth of fully oxidized films. By use of a plasma source of oxygen, O atoms and ions are provided to the... 

Figure 9.1. XRD pole figures indicate that a ceria film grown by OPA-MBE on SrTtO, with (001) epitaxy, is highly oriented azimuthally (lop and middle). A small portion of the film is oriented to (111 epitaxy (bottom). From Kim cl al.

Experimentally one can fabricate advanced materials by depositing a material on a host lattice. In particular, ceria thin films, supported on a variety of substrates, have been synthesised using, for example, molecular beam epitaxy and chemical vapour deposition. Here, the...
