The diverse functional properties available in oxides have been established primarily through measurements on bulk samples. But when it comes to utilizing these properties in microelectronics, thin film synthesis techniques come into play and with them a different set of tricks are available to enhance the properties of oxides. Here I describe the use of reactive molecular-beam epitaxy (MBE) to synthesize multifunctional oxides, including ferroelectrics, ferromagnets, and materials that are both at the same time. (více ...)
