Abstract
Copper nanoparticles in carbon thin films (Cu NPs @ a-C: H) were prepared with various copper and carbon content by co-deposition of RF-sputtering and RF-PECVD method to use as catalysts for CNTs growth. The effect of carbon content on the catalytic properties of Cu NPs was investigated in this work. Although Cu NPs has no catalytic properties for CNTs growth, adding carbon improves the process of CNTs growth because of its effect on catalytic activity. In order to find copper and carbon content in the thin film, RBS analysis was used. These observations revealed by atomic force microscopic images. Moreover, scanning electron microscopy, transmission electron microscopy and Raman spectroscopy were performed for CNTs characterization. In this work, Cu NPs layers with various carbon contents were fabricated in the case of investigation on the catalytic properties.
