“…A similar value has been determined for δ3-MoN (P63mc, space group) by Ganin et al [36]. Mo5N6 is also superconducting with Tc equal to 12 K, whereas a lower value of 4 K has been determined for δ1-MoN (P6m2, space group).…”

“…The Mo5N6 crystalline solid would have a high superconducting temperature value Tc but this characteristic could be due to the contamination by δ3-MoN phase because of the low diamagnetic response [36]. As previously seen, owing to nitrogen vacancies and radiation damages induced by non-equilibrium processes, the predicted high superconducting structure cannot be synthesized.…”

“…The δ-MoN phase crystallizes at least in three different form of the hexagonal structure and one slightly overstoichiometric with composition Mo5N6. The various forms have been very accurately described in the paper by Ganin et al [36]. δ1-MoN has a WC-type crystal structure (P6m2, space group) with stacking faults of nitrogen atoms layers along the c axis due to nitrogen atoms disorder.…”

“…Ganin et al [36] have performed a very accurate study on molybdenum nitride phases of hexagonal structure deposited on wafers of microcrystalline hexagonal boron nitride. The experiments were carried out in a PECVD reactor with N2 gas and MoCl5 as a precursor at 266 Pa.…”

“…The thickness of films can reach 100 μm after a 16 h thermal treatment in NH3 flow [57]. According to the previously described works, the structure of substrates can be chosen to promote the structure of molybdenum nitrides: δ-MoN films/hexagonal BN [36] or δ-MoN/Al2O3 and γ-Mo2N/SrTiO3 [56].…”

Among transition metal nitrides, molybdenum nitrides have been much less studied even though their mechanical properties as well as their electrical and catalytic properties make them very attractive for many applications. The δ-MoN phase of hexagonal structure is a potential candidate for an ultra-incompressible and hard material and can be compared with c-BN and diamond. The predicted superconducting temperature of the metastable MoN phase of NaCl-B1-type cubic structure is the highest of all refractory carbides and nitrides. The composition of molybdenum nitride films as well as the structures and properties depend on the parameters of the process used to deposit the films. They are also strongly correlated to the electronic structure and chemical bonding. An unusual mixture of metallic, covalent and ionic bonding is found in the stoichiometric compounds.

In the last two decades, there has been a renewed interest in the chemistry of nitrides and nitridometalates. Both binary and higher nitridesMxNyhave already featured prominently as refractory materials, corrosion‐ and mechanical wear‐resistant coatings, hard materials, and hard magnets; thin films are used as diffusion barriers in integrated circuits.Whereas research on binary transition metal nitrides is mostly driven by technical and economic interests, the investigation on nitridometalates primarily focuses on exploration with respect to the development of new synthetic strategies and the design of new materials. Within this field of interest, especially the nitride chemistry of rare earth metals is still comparably undeveloped.Chemical bonding in binary nitrides varies from primarily salt‐like via covalent to metallic, whereas nitridometalates are best described as containing covalent complex anions [MxNy]z−with alkali, alkaline earth, or rare earth metal cations providing electroneutrality.
