Diamond like nanosized structures were deposited where a modified microwave plasma CVD diamond growth recipe was used; here, instead of a clean molybdenum (Mo) holder, the Si(100) substrates were placed on iron oxide coated Mo holder. The growth of micron size diamond crystals were observed on clean areas whereas rod shaped carbon based nanostructures were observed on iron oxide rich areas. Furthermore, the growth of CNTs was also noticed on the plasma exposed parts of the Mo holder. Electron microscopy results suggest that some of the nanorods crystallize in the form of diamond.
