摘要

The prospective utilization of nanoscale superconductors as microano-coils or circuits with superior current density and no electrical resistance loss in next-generation electronics or electromagnetic equipment represents a fascinating opportunity for new microsystem technologies. Here, a family of superconducting liquid metals (Ga-In-Sn alloys) and their nanodroplets toward printable and stretchable superconducting microanoelectronics is developed. By tuning the composition of liquid metals the highest superconducting critical temperature (T-c) in this family can be modulated and achieved as high as 6.6 K. The liquid metal nanodroplets retain their bulk superconducting properties and can be easily dispersed in different solvents as inks. The printable and stretchable superconducting microano coils, circuits and electrodes have been fabricated by inkjet printer or laser etching by using superconducting nanodroplets inks. This novel superconducting system greatly promotes the commercial utilization of superconductors into advanced flexible microanoelectronic devices and offers a new platform for developing more application with superconductors.
