M₂YSi (M=Rh, Ir): Theoretically predicted damage‐tolerant MAX phase‐like layered silicides

Searching for layered MAX phase‐like materials with properties of both ceramics and metals is a topic in its infancy. Herein, through a combination of crystal structure, electronic structure, chemical bonding, and elastic property investigations, we report two MAX phase‐like layered materials Rh 2 YSi and Ir 2 YSi. Rh 2 YSi and Ir 2 YSi have bulk modulus B of 150 and 185 GPa, respectively, which are comparable to the typical MAX phases like Ti 2...
