Intrinsic activation energy for twin wall motion
W. T. Lee, E. K. H. Salje, L. Goncalves-Ferreria +2
Even in a topologically perfect crystal, a moving twin wall will experience forces due to the discrete nature of the lattice. The potential energy landscape can be described in ter…
Landau Theory of Domain Wall Magnetoelectricity
Maren Daraktchiev, Gustau Catalan, James F. Scott
We calculate the exact analytical solution to the domain wall properties in a multiferroic system with two order parameters that are coupled bi-quadratically. This is then adapted…
Effects of carbon nanotubes on grain boundary sliding in zirconia polycrystals
M. Daraktchiev, B. Van de Moortele, R. Schaller +2
Mechanical properties of zirconia polycrystals decrease drastically at high temperature due to thermally activated grain boundary (GB) sliding, leading to plastic or even super-pla…
Effect of internal friction on transformation twin dynamics in SrxBa1-xSnO3 perovskite
M. Daraktchiev, E. Salje, W. Lee +1
The dynamics of transformation twins in SrxBa1-xSnO3 (x=0.6,0.8) perovskite has been studied by dynamical mechanical analysis in three-point bend geometry. This material undergoes…
How do the grains slide in fine-grained zirconia polycrystals at high temperature?
M. Daraktchiev, R. Schaller, L. Gremillard +3
Degradation of mechanical properties of zirconia polycrystals is hardly discussed in terms of solution-precipitation grain-boundary sliding due to experimental controversies over i…
Ultrathin Organic Transistors on Oxide Surfaces
Maren Daraktchiev, Adrian von Muehlenen, Frank Nuesch +4
In recent years, thin-film organic field-effect transistors (OFETs) have begun to be considered as a possible alternative to the hydrogenated amorphous silicon thin-film transistor…
