To address this, researchers are exploring advanced synthesis techniques, such as controlled radical polymerization and living anionic polymerization, which offer better control over molecular weight distribution and structural uniformity.

The cost-effectiveness of polysilane-based nanoelectronics is closely tied to the raw materials and processing methods used. Silicon, the primary component of polysilane, is abundant and relatively inexpensive. However, the purification and processing steps required to achieve the high levels of purity needed for nanoelectronics can significantly increase costs. Innovations in purification techniques, such as zone refining and chemical vapor deposition, are being developed to reduce these expenses while maintaining the necessary quality standards.

Energy consumption during the fabrication process is another crucial factor affecting both scalability and cost-effectiveness. Traditional methods of polysilane synthesis and device fabrication often require high temperatures and energy-intensive processes. Research into low-temperature synthesis routes and energy-efficient processing techniques is ongoing, with promising results in reducing overall energy requirements and associated costs.

The integration of polysilane-based components into existing semiconductor manufacturing processes presents both challenges and opportunities for scalability.
