WebJan 15, 2024 · Physical Properties of Diamond has a very high melting point (almost 4000°C). Very strong carbon-carbon covalent bonds have to be broken throughout the structure before melting occurs. is very hard. This is again due to the need to break very strong covalent bonds operating in 3-dimensions. doesn't conduct electricity. WebA formula is proposed for the effective density of states for materials with an arbitrary band structure. This effective density is chosen such that for nondegenerate statistics the conventional form n = Ne e −z where z = (E c ndash; E f )/kT remains valid. The result is applied for some simple cases, including the Kane band for InSb.
