   Sep 1, 2019 · High values of elastic modulus of MoSi 2-type C11 b structure are attributed to the pyramidal bonding state. Importantly, WSi 2 with C11 b, C49 and C54 structures show excellent electronic properties because of localized hybridization between W-5d state and Si-3p state at the Fermi level.
