“…First, the metal structure transforms from a hexagonal symmetry to a cubic symmetry when nitrogen is incorporated into the rhenium lattice. Second, our films deposited by reactive DC-sputtering are analogous to those deposited by Fuchigami et al [5] by means of laser ablation. Third, the cubic structure remains cubic for relatively large variations in the composition, as has been reported in the literature [5][6][7][8].…”

“…There is a threshold point at x ∼ 5/8; below that composition, the crystalline system can be cubic, while it is trigonal for higher compositions. In another report, tetragonal distortion is also considered [5]. Nevertheless, the high concentration of nitrogen in this arrangement is highly unlikely due to the high alloying energy, shown in Fig.…”

“…Those studies reported fcc crystalline structures, for compositions from x = 0.43 to x = 1. In another report where rhenium nitride films were made by the pulsed laser deposition method, the resulting structures could be either cubic or hexagonal [5]. With a low nitrogen content, x = 0.06, the film maintained a Relike hexagonal arrangement, while for x = 0.17 and x = 0.22, the films adopted cubic structures.…”

“…Because the deposition rate is very low, these films are grown over the course of 50 min. The Si substrate has peaks at 28.40 • (1 1 1) and 58.85 • (2 2 2), indicated with a * symbol in [5], with a o = 4.03 ± 0.03Å. For higher values of F N , the positions of peaks A through D shift to lower angles as the N/Re ratio in the films increase.…”

“…Until now, the nitrides of group VII have been scantily studied both theoretically and experimentally. Rhenium nitrides have been synthesized by several methods, including laser ablation [4,5], high-pressure high-temperature anvil cell reaction [6], the reaction of rhenium pellets with ammonia at high temperature [7], ion implantation of nitrogen into a rhenium foil [8] and reactive DC-magnetron sputtering, as we present here in this work. From the few reports available on the topic, the rhenium nitrides are expected to have exceptional properties, such as very high bulk moduli, high hardness and brittleness [9,10], catalytic activity [7], and superconductivity [8,11].…”

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.

Rhenium is both ar efractory metal and an oble metal that has attractive properties for various applications. Still, synthesis and applications of rhenium thin films have been limited. We introduce herein the growth of both rhenium metal and rhenium nitride thin films by the technologically important atomic layer deposition (ALD) method over awide deposition temperature range using fast, simple,a nd robust surface reactions between rhenium pentachloride and ammonia. Films are grown and characterized for compositions, surface morphologies and roughnesses,c rystallinities,a nd resistivities.C onductive rhenium subnitride films of tunable composition are obtained at deposition temperatures between 275 and 375 8 8C, whereas pure rhenium metal films growa t 400 8 8Ca nd above. Even aj ust 3nmt hickr henium film is continuous and has al ow resistivity of about 90 mW cm showing potential for applications for whicha lso other noble metals and refractory metals have been considered.
