dc.description.abstractCarbon, especially graphene quantum dots (GQDs) based electronics have become an attractive technology in recent years. The controlled modification of the electrical and optoelectronic properties of GQDs by physical/chemical processes or synthetic methods may lead to new applications. Gadolinium-doped polyethyleneimine (PEI) functionalized and nitrogen-doped graphene quantum dots (GdNPs-PEI@N-GQDs) are synthesized by a hydrothermal method to determine how doping carbon-based materials with Gd alters the electrical properties of the structure. The electrical properties of the GdNPs/PEI@N-GQDs nanocomposite-based diode are investigated using the current–voltage (I–V) technique and the capacitance and conductance voltage (C–V & G/ω–V) technique at 300 K in the frequency range of 0.5 to 500 kHz at ± 5 V. The rectification ratio (RR) is found to be 14 at a voltage of ±5 V. The rectifying behavior of the diode changes to an ohmic behavior after doping with Gd, compared to the Gd-free PEI@N-GQDs sample (2.8 × 104 at ±5 V). The results are expected to have an impact on the understanding of carbon-based electronics technology.en_US
