Seed 9


Synthesis of new topological Materials

This seed will use chemical concepts to predict and synthesize new quantum materials. Research will focus on Dirac and Weyl materials as well as two dimensional magnetic material. With combining chemical concepts such as electron counting and bonding rules with ab initio calculations, this research will identify the best candidates that will then be grown in single crystalline form to investigate the physical properties. For these studies, this seed will work in close collaboration with other groups within the MRSEC.
