Graphical abstract: Display Omitted Highlights: ► Branched, carbon nanofern like structure have been synthesized on glass substrate via PECVD. ► Ni catalyst played important role in growing such structure. ► The as prepared sample shows good field emission property with turn on field as low as 4.8 V/mm. ► Temperature dependent conductivity of the sample showed non-linearity. -- Abstract: Carbon nanofern-like structure was synthesized by direct current plasma enhanced chemical vapor deposition at 400 °C using acetylene as carbon precursor and nickel particle as seed. High resolution transmission electron microscopy (HRTEM) study confirmed the fern-like structure of the as-synthesized sample. It was seen that when nickel was not used a cluster deposition took place without forming any structure. Atomic force microscopy study showed the surface topology of the as-prepared samples. X-ray photoelectron spectroscopy as well as HRTEM studies confirmed the presence of nickel in the carbon matrix. Current (I)–voltage (V) characteristics have been taken for three different temperatures. A non-linear I–V characteristic was obtained for the fern like sample. Field emission study showed that carbon nanofern showed efficient field emission with a turn-on field as low as 4.8 V/μm. Also, the field emission has been studied for different inter-electrode distances.
