C, Si and Ge have same lattice structure. Why is C insulator, while Si

1.	C, Si and Ge have same lattice structure. Why is C insulator, while Si and Ge intrinsic semiconductors ?
Answer» Energy required to take out outer orbit electrons is less for Ge and Si but very large for C. so conduction electron is not easily available is not easily available for C and hence it is insulator .
