文摘
- •
GSs/Ag/TiO2 NTAs hybrid emitter was fabricated using electrochemical deposition process.
- •
The GSs/Ag/TiO2 NTAs exhibits good field emission performance with the low turn-on and threshold field, and good stability.
- •
GSs and Ag nanoparticles deposition on TiO2 NTAs increase the field enhancement factor and improve the contact resistance, respectively.
