The similar lattice constants and the shared common element (N) have inspired efforts to combine layers as epitaxial films. Scandium nitride and zirconium nitride have been employed as buffer layers between silicon substrates and GaN epitaxial films to block the initiation and Yttrium nitride is a dark gray powder, which is a kind of rare earth nitride. It has a very high melting point and keeps stable under high temperatures. So yttrium nitride can apply to refractory materials like titanium nitride and zirconium nitride. Yttrium nitride, Y5N14, was synthesized by a direct reaction between yttrium and nitrogen at ∼50 GPa and ∼2000 K in a laser-heated diamond anvil cell.

We measured their longitudinal-wave elastic constants CL between 20 and 300 K using picosecond ultrasound spectroscopy. Their room-temperature values are 945 ± 3 GPa and 930 ± 18 GPa for cBN and wBN, respectively. The shear modulus G of cBN was also determined by combining resonance ultrasound spectroscopy and micromechanics calculation as G Wurtzite boron nitride is a metastable superhard material that is a high-pressure polymorph of BN. Clarifying how the metastable high pressure material can be stabilized at atmospheric pressure is a challenging issue of fundamental scientific importance. Here, we fabricate millimeter-size w-BN bulk crystals via the hexagonal-to-wurtzite phase transformation at high pressure and temperatures. By combining transmission electron microscopy and ab initio molecular dynamics simulations, we reveal a s Micro-grains of wurtzite boron nitride(wBN) crystal have been observed in 5.0-7.0 GPa pressure and 1800-2000 K temperature where cubic boron nitride has been synthesized in a catalyst. The wBN grain size is about 20-30 nm. The presence of these micro grains indicates that the pressure for wBN growth could be lower than that found in the previous work. The first, wurtzite boron nitride, is similar to diamond but comprises different atoms. The second, the mineral lonsdaleite, is made from carbon a Wurtzite Boron Nitride (wBN) is a wide band gap BN polymorph with unique mechanical properties such as hardness and stiffness. Initially synthesized in 1963 by transforming hexagonal BN (hBN) under high temperature and pressure conditions, wBN can now be stabilized at atmospheric pressure to obtain high-quality samples. Our first-principles study investigates the electronic, vibrational, and optical properties of wBN across a broad range of pressures. We account for the electron-hole interaction

Film Deposition of Silicon Nitride

What is Silicon nitride?Silicon nitride is a chemical compound of the elements silicon and nitrogen. Si3N4 is the most thermodynamically stable and commercially important of the silicon nitrides, and the term "silicon nitride" commonly refers to this specific composition. It is a white, high-melting-point solid that is relatively chemically inert, attacked by dilute HF and hot H3PO4. It is very hard (8.5 on the Mohs scale). It has high thermal stability with strong optical nonlinearities for all

Hexagonal BN can be prepared as fibers, structurally similar to carbon fibers, sometimes called "white carbon fiber." They can be prepared by the thermal decomposition of extruded borazine fibers by adding boron oxide in nitrogen at 1800 °C.

Preparation of cubic Boron nitride

Cubic boron nitride is produced by treating hexagonal boron nitride at high pressure and temperature, much as synthetic diamond is made from graphite. Direct conversion of hexagonal boron nitride to the cubic form occurs at pressures up to 18 GPa and temperatures between 1730-3230 °C; the addition of a small amount of boron oxide can lower the required force to 4-7 GPa and temperature to 1500 °C. Industrially, BN conversion using catalysts is used instead; the catalyst materials differ for diffe

Hexagonal Boron nitride

The graphite-like polymorph of boron nitride, hexagonal boron nitride, h-BN, α-BN, or g-BN (graphitic BN), sometimes called "white graphite," is the most widely used. The hexagonal polymorph is composed of layers of hexagonal sheets analogous to graphite. However, the interlayer "registry" of these sheets differs from the pattern seen for graphite because the atoms are eclipsed, with boron atoms laying over and above nitrogen atoms. This registry reflects the polarity of the B-N bonds. The dimin
