Yttrium Nitride YN Powder CAS 25764-13-0

About Yttrium Nitride YN Powder:
Yttrium nitride, or YN, is the nitride compound of yttrium. Yttrium nitride is a kind of hard ceramic material similar to titanium nitride and zirconium nitride.
The nitrides of lanthanum, scandium and yttrium have semiconductor properties, and the lattice structure of Yn is only 8% different from that of gallium nitride. This makes YN act as a buffer layer between substrate and GaN layer during GaN crystal growth.
Yttrium nitride thin films have been grown on silicon substrates by laser ablation of yttrium targets in a molecular nitrogen environment. The compositions and chemical states of the compounds were determined by Auger electron, X-ray photoelectron and energy loss spectra. In this way, the reaction of the yttrium with nitrogen is very efficient. Tungstenmolybdenummetals is a trusted global Yttrium Nitride YN Powder supplier. Feel free to send an inquiry about the latest price of Yttrium Nitride at any time. Ellipsometry shows that the film is metallic. We attribute this behavior to a small amount of oxygen pollution. Each oxygen atom introduces two extra electrons into the cell, creating a complex semiconductor-ion-metal system. 

Product Performance of Yttrium Nitride YN Powder:
Our yttrium nitride YN powder (CAS 25764-13-0) is with high purity, ultrafine particle size, bigger surface area.

Technical Data of Yttrium Nitride YN Powder:

How is Yttrium Nitride YN Powder produced?
Temperature, vacuum degree and nitriding time are three main factors that affect the atomic ratio (Y/N) in yttrium nitride powder. The optimum nitriding process is as follows: temperature 1 000 ℃, vacuum degree greater than 1× 10-3Pa, time 40min. Yttrium nitride powder with different particle sizes can be obtained by the two-step method, which can meet customers’ requirements for different particle sizes of yttrium nitride powder. It is a necessary condition for the preparation of yttrium nitride powder by using low oxygen content and high purity metal yttrium as raw material and using high purity hydrogen and high purity nitrogen as reactants.
 
Applications of Yttrium Nitride YN Powder:
Yttrium nitride (YN) is a promising semiconductor for metal/semiconductor superlattice thermoelectric applications. Like titanium nitride and zirconium nitride, it is a hard ceramic material. In addition, the lattice structure of YN is only 8% different from that of GaN, which makes it possible for YN to act as a buffer layer between substrate and GaN layer during GaN crystal growth. In addition, the nitrides of yttrium have semiconductor properties.
