Abstract

Three-dimensional metal oxides/Ni₃C structures (TiO₂/Ni₃C, CuO/Ni₃C, and WO₃/Ni₃C) are prepared in situ on the macroporous electrically conductive network (MECN) and the field emission (FE) characteristics are investigated systematically. The TiO₂/Ni₃C nanosheets deposited on MECN show the smallest turn-on and threshold fields of 1.30 V/μm and 1.69 V/μm, respectively, compared to CuO/Ni₃C and WO₃/Ni₃C. The excellent FE properties of TiO₂/Ni₃C/MECN arise from the low work function and change in hybridization from sp² to sp³ carbon atoms at the electron emission sites. In situ synthesis of TiO₂/Ni₃C is environmentally friendly, efficient, and compatible with microelectronics manufacturing boding well for application to high-performance FE and vacuum nanodevices.
