Abstract: This study investigates the application of Quantum Dots (QDs) in microcircuit architectures to enhance electronic performance by overcoming the limitations of conventional silicon-based systems. Quantum dots, with their tunable bandgap and unique quantum confinement properties, enable efficient charge transport, reduced energy dissipation, and improved thermal stability. High-purity CdSe/ZnS and PbSe QDs were synthesized and integrated into microcircuit substrates using controlled deposition and lithographic techniques. Structural, optical, and electrical characterizations were performed to assess their impact on device behavior. The results revealed a substantial increase in charge carrier mobility, a significant reduction in switching delay, and improved energy efficiency compared to control circuits. Moreover, QD-integrated devices exhibited superior thermal and cycling stability, maintaining over 95% of their initial performance after prolonged high-temperature operation. Statistical analysis using one-way ANOVA confirmed that the performance enhancements were significant across all measured parameters. The findings demonstrate that QDs can be seamlessly incorporated into existing CMOS fabrication processes without major structural modifications, offering a scalable route for next-generation electronics. Practical recommendations for optimization include precise QD size control, interface engineering, and the adoption of scalable deposition techniques. Overall, this work highlights the potential of QD-based microcircuits to drive advancements in high-speed, low-power, and thermally robust electronic systems suitable for communication, computing, and optoelectronic applications.
