Metastability relationships ranging from several- and you may three-dimensional amazingly structures: an incident examination of the new Cu-situated ingredients

Metastability matchmaking ranging from two- and you can about three-dimensional amazingly formations: a case study of the new Cu-depending ingredients

Some of the about three-dimensional (3D) amazingly formations try built by the stacking several-dimensional (2D) layers. To examine if that it mathematical layout, we.e., having fun with 2D levels due to the fact foundations to have three dimensional formations, can be applied in order to computational information structure, we commercially have a look at the newest dynamical stability away from copper-created compounds CuX (a metallic element X) in the B \(_h\) and you can L1 \(_1\) formations constructed from this new buckled honeycomb (BHC) framework as well as in the brand new B2 and you will L1 \(_0\) formations made out of the new buckled rectangular (BSQ) framework. We reveal that (i) in the event that CuX throughout the BHC construction are dynamically steady, those who work in the brand new B \(_h\) and you can L1 \(_1\) formations also are steady. Playing with molecular figure simulations, we like demonstrate that CuAu regarding B \(_h\) and you will L1 \(_1\) structures withstand temperatures as high as 1000 K. While the interrelationship of your own metastability involving the BSQ in addition to 3d formations (B2 and L1 \(_0\) ) isn’t obvious, we find one to (ii) in the event the CuX throughout the B2 (L1 \(_0\) ) build are dynamically secure, you to about L1 \(_0\) (B2) try volatile.
