Research Vision
Our research is driven by the goal of developing innovative processes for the mass production of nanowires and seamlessly integrating them into highly efficient energy conversion and mechanical devices. We are focused on fabricating advanced thermoelectrics, solar cells, and photocatalytic systems, utilizing semiconductor nanowires as the core component. Additionally, we aim to design and create ‘smart’ mechanical devices from nanowire-based composites.
Characteristics desired of nanowires and nanowire-based devices and system for the mass production and deployment of energy conversion devices based on bulk nanowire assemblies. The vision of our work is to impart nanowires and nanowire-based systems all the above desired characteristics.
Mass Production of Nanowires
The first phase of our vision involves the creation and implementation of novel processes for producing nanowires with controlled diameters and morphologies. These nanowires must exhibit high resistance to air and moisture degradation without compromising their electrical or electronic properties. Our goal is to achieve surface stability for nanowires while maintaining their essential characteristics.
Large-Scale Assembly and Device Fabrication
The second phase focuses on developing strategies for the large-scale assembly of nanowires in an interface-engineered manner, facilitating their direct use in electronic device fabrication. We aim to minimize post-processing steps to convert nanowires into functional energy conversion devices. By designing methods for assembling nanowires in both randomly-oriented and aligned configurations without altering their morphologies or dimensions, we ensure that the unique properties of individual nanowires are preserved and extended to larger assemblies. Engineering the interfaces between nanowires within these assemblies will help translate their novel properties into practical applications.
Widespread Application and Scalability
Our overarching objective is to enable the large-scale production of nanowire-based energy conversion and mechanical devices, making them accessible and affordable for widespread use. By achieving efficient, reliable, and reproducible production processes, we envision a future where nanowire-based devices are as commonly available as everyday products like aspirin. To support widespread terrestrial deployment, we also emphasize the importance of identifying avenues for recycling nanowire-based devices. This vision encapsulates our commitment to advancing nanowire technology for the benefit of mankind, promoting sustainable and scalable solutions for energy and mechanical applications.
