Graphene is a two-dimensional network in which sp(2)-hybridized carbon atoms are arranged in two different triangular sub-lattices (A and B). By incorporating nitrogen atoms into graphene, its physico-chemical properties could be significantly altered depending on the doping configuration within the sub-lattices. Here, we describe the synthesis of large-area, highly-crystalline monolayer N-dope...
This paper is an attempt to synthesize nanostructured tantalum films on medical grade AISI 316L stainless steel (SS) using pulsed DC plasma assisted chemical vapor deposition (PACVD). The impact of duty cycle (17-33%) and total pressure (3-10 torr) were studied using field emission scanning electron microscopy (FESEM), grazing incidence x-ray diffraction (GIXRD), nuclear reaction analysis (NRA)...
We have used laser-initiated chemical vapor deposition to grow the chromium oxide thin films through the oxidation of Cr~CO!6 in an oxygen environment. While both Cr2O3 and CrO2 are present in the film, the relative weight of each phase depends on the oxygen partial pressure. The Curie temperature of the film increases and approaches the bulk TC of CrO2 ~397 K! as the partial oxygen pressure is...
This paper gives some insights in the applications where PECVD nitrides can be introduced to replace the LPCVD layers and how the process parameters need to be varied to obtain the desired properties. Film properties like stress, hydrogen content, wet etch rate and deposition rate are reported. The nitrides are optimized for specific applications and examples on the influence of nitride propert...
