Can we make stable structure by depositing TiO2 film on SrTiO3, so that Sr atoms do not diffuse in TiO2?

09 September 2015 0 4K Report

I want to ask that when we deposit TiO2 on SrTiO3 film then both films have large lattice mismatch. Is there any idea to make the structure stable? So that, no diffusion of Sr atoms may take place from SrTiO3 film to TiO2?

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

Should I include H atom into C3N5 when i am doing DFT modelling?

Hi all, my experimental XPS results shown that my C3N5 sample consists of N-H bond, hence in this case I should incorporate the N-H bond into my DFT modelling. However, I do notice several papers...

What procedure should I follow for current controlled PPy film electrochemical deposition on ITO?

For example, I perform passivation process before electropolymerization of Py for adhesion to titanium surface. Is a similar or different procedure required for ITO? If necessary, I would be glad...

Why reactivity isn't increased with more empty spots in valence shell?

If from a geometric perspective the non-halogens, non-noble gases have more empty spots in their valence shell, and the filling/exiting of any of the empty spots in the shell constitutes a...
