Contribution

The paper introduces a novel method for preparing films with discrete nano-DLC particles and demonstrates their effective field emission performance.

Findings

High sp3 ratio (86%) in nanoparticles

Achieved current density of 1mA/cm2 at 10.2V/μm

Discretely distributed nanoparticles on silicon substrate

Abstract

The films with the discrete diamond-like-carbon nanoparticles were prepared by the deposition of the carbon nanoparticle beam. Their morphologies were imaged by Scanning Electron Microscopy (SEM) and Atomic Force Microscopy (AFM). The nanoparticles were found distributed on the silicon (100) substrate discretely. The semisphere shapes of the nanoparticles were demonstrated by the AFM line profile. EELS was measured and the sp3 ratio as high as 86% was found. The field-induced electron emission of the as-prepared cascade (nanoDLC/ Si) was tested and the current density of 1mA/cm2 was achieved at 10.2V/{\mu}m.
