Superconducting WS2-based nanosheet ink for printable and flexible electronics
Princeton Docket # 22-3910-1
Researchers at Princeton University have developed a novel printable nanosheet ink that represents a significant advancement in nanomaterial technology. Previous research in 2D material inks has primarily focused on graphene-based solutions, which have shown promise but often struggles with stability, conductivity, or substrate compatibility issues. This ink's unique composition, which consists of atomically thin 2D materials with large surface areas, ensures excellent connectivity and conductivity in the printed patterns at room temperature, while also exhibiting superconducting properties below 7.3K. Furthermore, the ability to transform the printed sheets into semiconducting 2H-WS2 through laser radiation or thermal activation adds an extra layer of functionality and adaptability. Its potential uses span from 3D printing and flexible electronics to integrated circuits and quantum computing processes and product capabilities. The ink's stability and compatibility with various substrates, combined with its unique electrical properties, position it as a superior alternative to current conductive inks, potentially enabling the development of more efficient, compact, and versatile electronic devices and components.
