Hi I am an absolute beginner to Comsol and I am working on thin film capacitor simulation.

Does anyone work with Ba0.6Sr0.4TiO3 as a dielectric material?
I want to simulate the capacitance of capacitor but I do not know what properties to set
in Ba0.6Sr0.4TiO3 material..

Could anybody help me on this?

Thank you

Hi

material properties, particularly for multi physics are often difficult to find. probably here are not many out here reading and using your material, or it's perhaps also that that kind of material has properties that are very much deposit technology dependent. The bst is to seach the scientific litterature, or matweb or whatever to get the basic material properties

Good luck

Thank you Ivar :)

I have searched the BST material properties, however I am not sure which properties are important to include.

Hi

that all depends on the physics you choose and the variables you scan ofr your model:
- can you do with scalars ?,
- do you need anisotropic values? ,
- does the temperature T have an inluence ?,
- the electric field ?
- hte magnetic field ?
- ...

In anycase start simple, then complexify when the simple model works and add one level at the time, this given best chances to converge

Thank you so much for your advice..

I'll try from a simple start then.

Have a good day
