Molybdenum nitride nanoparticles high-resolution transmission electron microscopy study Academic Article uri icon


  • The structure and size of molybdenum nitride nanoparticles were investigated using high-resolution transmission electron microscopy (HRTEM). Typical sizes of the particles were between 3 and 5nm and they were mostly clustered together. High-resolution lattice imaging shows that the particles are single crystalline in nature and defect free. Two different phases of molybdenum nitride, -Mo 2 N (cubic) and -MoN (hexagonal) were identified. In addition, body centered cubic molybdenum phase was also present. It is anticipated that molybdenum is formed because of insufficient N 2 supply or slow reaction rate. A mixture of -Mo 2 N and -MoN suggests the existence of a temperature gradient in the chamber leading to formation of -Mo 2 N at lower temperature (500 to 700C) and -MoN at higher temperature (850C). 2007 Elsevier B.V.
