High-pressure synthesis and crystal structures of molybdenum nitride Mo₃N₅ with anisotropic compressibility by a nitrogen dimer

Abstract

A novel high-pressure molybdenum nitride phase, Mo3N5, was synthesized at above 45 GPa via nitridation reaction for molybdenum with nitrogen under high pressure using a laser-heated diamond anvil cell. Mo3N5,...

A theoretical investigation on the structural stability, superconductivity, and optical and thermodynamic properties of Ir2P under pressure

“…4 Some promising candidates, such as OsB 2 , Ir 4 B 5 , ReB 2 , WB 4 , TaC, ReC, ReC 2 , Zr 3 N 4 , and Mo 3 N 5 have been experimentally synthesized and studied. [5][6][7][8][9][10][11][12][13] Firstprinciples density functional theory (DFT) calculations are a powerful tool for predicting the structural, electronic, elastic, and thermodynamic properties of carbides, nitrides and borides with transition-metal elements in a large region of the periodic table. [14][15][16][17][18][19][20][21][22][23] However, the study of transition-metal phosphides (TMPs), especially noble-metal phosphides, is relatively limited.…”

High‐pressure Synthesis of Cobalt Polynitrides: Unveiling Intriguing Crystal Structures and Nitridation Behavior

“…[1][2][3] These compounds have recently undergone extensive investigation through high-pressure experiments, where they were synthesized in laser-heated diamond anvil cells. [1][2][3][4][5][6][7] Transition metal pernitrides (e. g. PtN 2 , ReN 2 , OsN 2 ) containing NÀ N dimers are recognized for their high bulk modulus and potential applications as superhard materials. [1,8,9] Polynitrides containing polymeric nitrogen chains (such as FeN 4, [2] TaN 5, [10] MgN 4, [11] WN 10, [12] YN 6 [13] ) represent higher levels of nitridation.…”

“…[17,23] Numerous experimental studies had demonstrated a wealth of polymorphs of transition metal nitrides at different pressure and temperature conditions. [4,6,21,22] However, to uncover the nitridation path, the nitridation behavior of transition metals at high-pressure needs to be explored.…”

Molybdenum Thin Film Formation from Molybdenum Nitride Deposited by Plasma-enhanced Atomic Layer Deposition with Hydrogen-permeable Mechanical Capping Layer

“…Mo thin film deposition via sputtering has been reported; however, it is limited in demonstrating nano-scale or 3-dimensional structured devices. Since Mo has various stable oxidation states and is facile to form compounds, such as molybdenum carbide , and molybdenum nitride, − it is hard to perform Mo metal deposition using chemical reaction-based deposition processes, such as chemical vapor deposition and atomic layer deposition (ALD). Post process to reduce the Mo compound thin film to Mo metal has been investigated, , but it suffers from morphology degradation by Mo metal migration.…”
