Field emission characteristics of MWCNT- bimetal (Cu and In) hybrids: Correlation with morphology, microstructure and electronic structure

Excellent field emission with enhanced photodetection behavior of multiwalled carbon nanotubes: experimental and theoretical study

“…Saini et al synthesized vertically aligned multiwalled carbon nanotubes (MWCNTs) and bi-metal (Cu and In) decorated CNTs and the In–Cu–MWCNTs demonstrated a notable increase in current density to 7.46 mA cm −2 when compared to the 2.83 mA cm −2 of pristine CNTs. 35 For example, regarding the CNT axis, the optical absorption can be maximized or suppressed depending on the direction of polarization. The second distinction worth noting results from the quasi-one-dimensional material's heightened Coulomb interaction, which causes a large exciton binding energy that is predominant in the visible, near, and mid-infrared optical absorption in CNTs.…”
