Abstract In this study, Ag-doped graphene oxide (GO:Ag) nanoparticles were successfully synthesized via an eco-friendly bacterial reduction method, marking the first reported use of biological approach in GO:Ag nanocomposite fabrication. The nanoparticles, characterized by TEM, revealed Ag particles ranging from 45 to 70 nm homogeneously distributed on GO sheets. These nanocomposites deposited both glass and p-type silicon (p-Si) substrates using a controlled drop-casting method at 300 °C form uniform thin films. Optical measurements indicated narrowed band gap 0.75 eV, attributed electronic interaction between GO. XRD Raman analyses confirmed presence crystalline cubic-phase within hexagonal lattice. SEM EDX results showed dispersion 47–78 nanospheres throughout film. Cross-sectional analysis further typical wrinkled, sheet-like morphology layers, confirming their retention layered stacking during film formation. resulting films integrated as interfacial layer Ag/GO:Ag/p-Si/Ag diode structures. Electrical characterizations under ambient conditions demonstrated rectifying behavior, with calculated parameters including ideality factor 2.30, barrier height 0.76 saturation current 1.78 × 10 −17 A. Capacitance–voltage (C–V) provided insights into doping concentration, diffusion potential, interface quality. findings validate potential biologically sustainable, low-cost, effective material for future nanoelectronic device applications.
