摘要: Field emission (FE) properties of indium-decorated vertically aligned multi-walled carbon nanotube (MWCNT) films are investigated. The superior FE achieved for 4-nm-thick indium-coated MWCNTs as compared to those coated with higher thicknesses indium and pristine CNTs. Optimization in the is primarily attributed transformation sp2- sp3-hybridized carbons thickness. Other factors important better enhanced density states near Fermi level slightly improved field enhancement factor at relatively low applied electric fields.
