“…Thus, needle-like SnO 2 nanograsses have highly efficient fieldemission. Moreover, compared to turfgrass-like SnO 2 nanograsses, needle-like SnO 2 nanograsses exhibit good FE properties due to the high aspect ratio, nano-sized sharp corners [23]. These comparative results demonstrate that the FE performance is strongly influenced by the SnO 2 morphology on GOs.…”

a b s t r a c tDifferent SnO 2 nanograsses have been successfully synthesized on graphene oxide sheets (GOs) by a hydrothermal method. The morphologies and compositions of as-synthesized SnO 2 nanograsses on GOs (SNGs) were characterized by X-ray powder diffraction (XRD), X-ray energy dispersive spectrometer (EDS) and field-emission scanning electron microscopy (FE-SEM). By adjusting the volume ratios of ethanol in the ethanol-water solvent (r), the morphologies of SNGs were highly manipulated. The field emission (FE) properties of SNGs were measured and found to be strongly influenced by the morphologies of SnO 2 . The needle-like SNGs have efficient FE properties with a low turn-on electric field of 5.23 V μm À 1 and a high field enhancement factor of 2388 among all the samples.

Field‐emission cold cathodes are the key components of vacuum nanoelectronics that offer great advantages over other electron sources based on the thermionic or photoelectric effects. In the effort to realize new electron sources, a systematic investigation of the field emission (FE) properties of SnO2 nanofiber networks is performed. High‐purity SnO2 nanofibers, confirmed by X‐ray photoelectron spectroscopy, are prepared by electrospinning technique and then uniformly distributed over Si wafer. Field emission properties are investigated using a nanomanipulated tip‐shaped anode, inside a scanning electron microscope, for fine tuning the anode‐cathode separation distance. A field‐emission current is observed with an applied electric field as low as 25 V μm−1. Performance parameters such as turn‐on field and field enhancement factor are evaluated within the theoretical Fowler–Nordheim framework as a function of the anode–cathode separation distance, demonstrating that a maximum enhancement factor of about 150 is obtained at a separation of 200 nm. The emission from a single nanofiber is characterized by a current saturation at high voltages that can be explained in terms of electron supply limitation within conduction band. No evidence of field emission current contribution by electron tunneling from the valence band is observed in the experimental data.
