Integrating superconducting van der Waals materials on paper substrates.

Area of Science:

• Materials Science
• Condensed Matter Physics
• Nanotechnology

Background:

• Paper offers a significantly cheaper alternative to silicon for electronic components.
• Van der Waals materials are promising for paper-based electronics due to their electrical and mechanical properties.
• Integrating superconductors onto paper substrates has remained a significant challenge.

Purpose of the Study:

• To demonstrate the deposition of a van der Waals superconductor onto standard copy paper.
• To investigate the superconducting properties of the deposited material on a paper substrate.
• To explore the potential for low-cost, flexible superconducting electronics.

Main Methods:

• Deposition of niobium diselenide (NbSe2), a van der Waals superconductor, onto standard copy paper.
• Characterization of the deposited NbSe2 films for superconducting properties.

Main Results:

• Successful deposition of NbSe2 films on copy paper.
• The NbSe2 films exhibited superconducting properties comparable to bulk NbSe2.
• Observed Meissner effect and a drop to zero resistance below the critical temperature.

Conclusions:

• Paper can serve as a viable substrate for van der Waals superconductors.
• This research paves the way for low-cost, flexible superconducting electronic devices.
• The findings overcome a key limitation in paper-based electronics integration.
