with the lowest formation energy. However, it seems there was a mismatch between the material IDs requested and the material IDs returned in the output. The Young's modulus values are not provided, but the bulk modulus can be a good indicator of stiffness. The material with the highest bulk modulus would be considered the stiffest. From the provided output, the SiO2 with material ID mp-9258 has the highest bulk modulus of 310.27 GPa, which suggests it is the stiffest among the listed materials. Since this material also belongs to the Si-O system and has a high bulk modulus, it is likely to be one of the stiffest materials with low formation energy in the Si-O system.
