| dc.description.abstract | The structural, electronic and 
magnetic properties of NbN are studied by ab initio method by considering the four polymorphs 
{B1 (rock salt), B4 (wurtzite), B81 (NiAs) and Bh 
(WC-type)} of NbN. The results show that 
structurally, B81 is more stable since it has the 
least total energy per formula unit volume. The 
enthalpies of the polymorphs in relation to 
pressure increases from B81<B4<Bh<B1 
respectively. It is also observed that the four 
structures have negative enthalpies; meaning 
they can be produced at ambient conditions. The 
calculated density of states and band structures 
indicate that the four polymorphs are metallic, 
while the magnetic moment implies that the four 
are non-magnetic. | en_US |
