Yttrium nitride - Wikipedia
Yttrium nitride, YN, is a nitride of yttrium. Yttrium nitride is hard ceramic material similar to titanium nitride and zirconium nitride. The nitrides of lanthanum, scandium, and yttrium show semiconducting properties and additionally the lattice structure of YN differs only by 8% from that of gallium nitride. This makes YN a possible buffer ...

Sublimation crystal growth of yttrium nitride - ScienceDirect
2010年10月1日 · The sublimation–recombination crystal growth of bulk yttrium nitride crystals is reported. The YN source material was prepared by reacting yttrium metal with nitrogen at 1200 °C and 800 Torr total pressure.
Stable nitrogen-rich yttrium nitrides under high pressure
2022年12月15日 · Yttrium is a lighter element among the transition metals (only after scandium) so it is relatively small in the nitride which contributes to higher nitrogen content. In addition, Y can provide 2 outer shell s electrons which meet the need of N.
The Influence of Niobium and Zirconium Addition on the …
2023年12月13日 · Yttrium nitride (YN) is a semiconductor composed of yttrium (Y) and nitrogen (N), and it belongs to the larger category of nitride compounds [1]. It is currently used in a wide range of applications. Silicon nitride powders are coated uniformly with yttria and yttria–alumina precursors using YN in microencapsulation procedures [2].
First-principles calculations to investigate structural, elastic ...
2021年9月1日 · The X–X (W–W) direct band gap in scandium (yttrium) nitride translates its semiconductor character in the zinc blend structure. The N: p orbit and small contribution of Sc: d (Y: d) site are responsible to the optical modes, while Sc: d (Y: d) site and small contribution of N: p orbit are the sign of acoustical modes.
Structural, optoelectronic, and thermodynamic properties of Y
2015年11月30日 · These studies indicate that yttrium nitride can be used in the production of long-wavelength optoelectronic devices, electric contact, and diffusion barrier. On the other hand, III–V ternary alloys have received increased attention in the last decades, and new strategies for the synthesis of nanocrystalline systems have been reported [ 11 ].
Dense Structure of Yttrium Nitride as a Post-Rock-Salt Phase: …
The post-rock-salt (B1) phase in yttrium nitride was investigated under pressures above 100 GPa. The starting B 1 phase was prepared by a direct elemental reaction between yttrium metal and supercritical nitrogen in a laser-heated diamond anvil cell.
Ab initio calculations of yttrium nitride: structural and electronic ...
2009年5月5日 · Using first principles total energy calculations within the full-potential linearized augmented plane wave method, we have studied the structural and electronic properties of yttrium nitride (YN) in the three phases, namely wurtzite, caesium chloride and rocksalt structures.
Yttrium Nitride - American Elements
The yttrium atom has a radius of 180 pm and a Van der Waals radius of 219 pm. Yttrium was discovered by Johann Gadolin in 1794 and first isolated by Carl Gustav Mosander in 1840. In its elemental form, Yttrium has a silvery white metallic appearance. Yttrium has the highest thermodynamic affinity for oxygen of any element.
