Comparison of Carbon with Silicon – Every Science

Comparison of Carbon with Silicon. by Andrew. Diamond is an insulator, but silicon is a semiconductor. This is because the band gap in Si is smaller than that in C. There is no Si analogue of graphite; the larger size if the Si atom means that the overlap of the Si p-orbitals is poor, and hence that Si pπ-pπ bonding is poor.
