Abstract
The first five members of the Srn+1TinO3n+1 Ruddlesden-Popper homologous se ries, i.e., Sr2TiO4, Sr3Ti2O7, Sr4Ti3O10, Sr5Ti4O13, and Sr6Ti5O16, have be en grown by reactive molecular beam epitaxy. A combination of atomic absorp tion spectroscopy and reflection high-energy electron diffraction intensity oscillations were used for the strict composition control necessary for th e synthesis of these phases. X-ray diffraction and high-resolution transmis sion electron microscope images confirm that these films are epitaxially or iented and nearly free of intergrowths. Dielectric measurements indicate th at the dielectric constant tensor coefficient epsilon (33) increases from a minimum of 44 +/-4 in the n=1(Sr2TiO4) film to a maximum of 263 +/-2 in th e n=infinity (SrTiO3) film.
