C, Si and Ge have same lattice structure...

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

Text Solution

Verified by Experts

In carbon the four bonding electrons are d present in second orbit . However in casae of Si and and Ge , these four bonding highest for C and free electrons in case of C are neglightly availble for conduction.
