Ferroelectric Domain Structure of La-modified Lead Titanate Ceramics
14 Dec 2018 | Contributor(s):: Brian Demczyk, G. Thomas
Presentation describes the ferroelectric domain structure of Lanthanum-modified lead titanate ceramics, as deduced by transmission electron microscopy, including the ferroelectric to paraelectric phase transformation. A significant result was the observation of a minimum grain size for...
Structure and Morphology of Silicon-Germanium Thin Films
07 Feb 2015 | Contributor(s):: Brian Demczyk
This presentation describes the growth of (Si,Ge & SiGe) thin films on Si and Ge (001) and (111) substrates by ultrahigh vacuum chemical vapor deposition (UHVCVD). Thin films were characterized structurally by conventional and high-resolution transmission electron microscopy (TEM) and...
