Improving Fatigue Strength of Alumina through Surface Grading

May 9, 2011
Author(s)
Yvonne B. Gerbig, Linlin Ren, Lela Liu, Sanjit Bhowmick, Malvin Janal, Van Thompson, Yu Zhang
Porcelain veneered alumina crown restorations often fail from bulk fracture resulting from radial cracks that initiate at the cementation surface with repeated flexure of the stiffer crown layers on the soft dentin support. We hypothesize that bulk

Measurement of residual stress field anisotropy at indentations in silicon

June 23, 2010
Author(s)
Yvonne B. Gerbig, Stephan J. Stranick, Robert F. Cook
The residual stress field around spherical indentations on single crystal silicon (Si) of different crystallographic orientation is mapped by confocal Raman microscopy. All orientations exhibit an anisotropic stress pattern with an orientation specific

Combinatorial study of the crystallinity boundary in the HfO2-TiO2-Y2O3 system using pulsed laser deposition library thin films

May 16, 2008
Author(s)
Peter K. Schenck, Jennifer L. Klamo, Nabil Bassim, Peter G. Burke, Yvonne B. Gerbig, Martin L. Green
HfO2-TiO2-Y2O3 is an interesting high-k dielectric system. Combinatorial library films of this system enable the study of the role of composition on phase formation as well as optical and mechanical properties. A library film of this system deposited at
