General Questions and Answers / Strain on building interface
« on: June 30, 2016, 22:34 »
Hi,
I'm new to using the VNL (which is BTW Awesome!) and was wondering if someone can help me out with this question that is bugging me.
When I make an interface using two different materials, there are four strain number that show up in the interface builder: e11, e22, e12 and the average.
Q: Should one consider the "Mean Absolute Strain" as the determining factor for how good lattice matching is? OR Should all other three strains (i.e. e11, e22 and e12) needs to be small for a good lattice matching of the two interface?
Thank you for any input.
best,
Nitin
