Thus they demonstrated the production of nuclei of barium, lanthanum, strontium, yttrium, and, more recently, of xenon and cæsium.

For the buffer layers, they considered using CdS as well as new alkaline earth metal chalcogenides such as magnesium sulfide (MgS), calcium sulfide (CaS), strontium sulfide (SrS), and barium ...

Their findings, published in the journal “Science Advances,” described a lattice arrangement of three different layers of ferroelectric crystals (in this case, of barium titanate, strontium ...
