Diamond properties are significantly affected by crystallite size. High surface to volume fractions result in enhanced disorder, sp 2 bonding, hydrogen content and scattering of electrons and phonons. Most of these properties are common to all low dimensional materials, but the addition of carbon allotropes introduces sp 2 bonding, a significant disadvantage over systems such as amorphous silicon.
