The use of nano-carbon metal matrix composites can provide a solution to the enduring issue of optimal material selection and optimization for getting metal-insulator transition (MIT) behavior at a particular frequency at ambient temperature. Other substances, like two-dimensional (2D) transition metal dichalcogenides (TMD), vanadium oxide (VO2), and germanium telluride (Ge-Te), have difficult challenges in achieving effectively the MIT property at a given frequency and temperature. It is also difficult to accurately explain the mechanism by which these materials acquire the MIT characteristic. In this demonstrated research work, nano-carbon doped aluminium oxide has been synthesized by chemical vapor deposition (CVD) methodology. The electrical properties of developed samples were measured by auto-lab PGSTAT with a frequency range of 10 μHz–32 MHz with a resolution of 0.003% whereas fractographical analysis of the samples was performed by scanning electron microscopy from Zeiss Evo 18. The experimental frequency response plots illustrated that nanocarbon doped alumina may be utilized as a low-pass filter for top frequency discontinuation at 9000 Hz in electronic industrial applications. The energy dispersive X-ray chemical analysis (EDS or EDX) of nano-carbon doped alumina showed a MIT development happens at 30% (by mass) nano-carbon doping in aluminium. The fractographical analysis of nano-carbon doped alumina revealed the minimum voids, defects, and porosity that cause marginal deviation in electrical properties at a higher temperature. As a result, this nano-carbon doped aluminium oxide material can be the future alternative to engineering materials for electronic industries such as high-frequency switches. Future research might examine the possibilities of various metal oxides doped with nano-carbon for higher cut-off frequency switches.
