Presentation Materials (1-6 of 6)

1. 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...

2. 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...

3. Evolution of Microstructure and Magnetic Properties in CoCr Thin Films

   25 Mar 2014 | | Contributor(s):: Brian Demczyk, J. O. Artman

   This presentation describes the structural and magnetic properties, including domain structures, in magnetron-sputtered Co-25% Cr thin films.

4. Structure and Properties of Carbon and Boron Nitride Nanotubes

   10 Jan 2014 | | Contributor(s):: Brian Demczyk

   This presentation describes structure and mechanical property determinations on carbon and boron nitride (sp2-bonded) nanotubes , as deduced by transmission electron microscopy.

5. Corrosion Mechanisms in Magnetic Recording Media

   29 Jul 2013 | | Contributor(s):: Brian Demczyk

   This presentation describes the corrosion process in longitudinal and perpendicular recording media, based upon electron and scanning probe microscopic analysis.

6. Texture-Induced hcp c-axis Alignment in Longitudinal Media
