Structural metastability and Fermi surface Topology of SrAl2Si2

Stamatios Strikos, Boby Joseph, Frederico G. Alabarse +4

SrAl2Si2 crystallizes into either a semimetallic, CaAl2Si2-type, αphase or a superconducting, BaZn2P2-type, βphase. We explore possible α--Pc;Tc--> βtransformations by employing pr…
