Studies of annealing impact on the morphological, opto-dielectric and mechanical behaviors of molybdenum-doped CrN coatings

Abstract

In the present study, molybdenum doped chromium nitride coatings deposited onto silicon substrates via unbalanced magnetron sputtering, in as-deposited and annealed conditions, at 500 -800 C in steps of 100 C, were studied to reveal their temperature dependent structural, morphological, optical and mechanical behaviors.An analysis of these features was carried out using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), ultraviolet visible (UV-Vis)

“…Metal nitrides (MNs) are important components of semiconductors and have been widely applied in electrocatalytic water-splitting, advanced electrochemical energy-storage and surface-coating technology [1][2][3][4][5][6][7][8][9][10][11][12][13]. Due to the variety of metal species and the difference in stoichiometry (nitrogen-lean phases and nitrogen-rich phases), MNs stand for a wide range of materials, including group-IIA nitrides (IIANs), group-IIIA nitrides (IIIANs) and transition metal nitrides (TMNs) [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29].…”
