<div dir="auto">Hello, are you sure you need the vacuum? You can just alternate the two materials and have 2 interfaces for the price of one.

I am planing to work on interfaces. In doing so, I want to keep few layers<br>
of a structure fixed while few to relax. In short this is what I am<br>
planning :<br>
<br>
10A vacuum<br>
2layers fixed<br>
4layers to relax<br>
2layers fixed<br>
<br>
How can I do this type of controlled dynamics?<br>
