چکیده انگلیسی
This study investigates the orientation of textured diamond films produced through microwave plasma chemical vapor deposition (MPCVD) at 1200Â W, 110Â Torr, CH4/H2Â =Â 1/20, with depositions times of 0.5-4.0Â h. After a growth period of 2.0-4.0Â h, this particular morphology revealed a rectangular structure stacked regularly on the diamond film. The orientation on {1Â 1Â 1}-textured diamond films grew a preferred orientation of {1Â 1Â 0} on the surface, as measured by XRD. The formation of the diamond epitaxial film formed textured octahedrons in ball shaped (or cauliflower-like) diamonds in the early stages (0.5Â h), and the surface of the diamond film extended to pile the rectangular structure at 4.0Â h. The width of the tier was approximately 200Â nm at the 3.0Â h point of deposition, according to TEM images. The results revealed that the textured diamond films showed two different morphological structures (typical ball shaped and rectangular diamonds), at different stages of the deposition period. The I-V characteristics of the oriented diamond films after 4.0Â h of deposition time showed good conformity with the ohmic contact.
