We report on the fabrication, structural, and electrical transport characterizations of superconducting nanowire arrays based on nano-laser direct writing. The thermal excitation-induced micro/nano fabrication based on the interactions between nano-laser direct writing and superconducting Nb films was experimentally analyzed and simulated.Experimentally, the arrays of superconducting nanowires have an area of 190 ×190 μm2 with a critical transition temperature Tc of 7.8 K and a critical current density Jc of 20.8 MA/cm2 at 4.0 K. The width and arrangement of the nanowires are precisely controlled, exhibiting a minimal loss of 0.6 K in Tc and excellent Jc after laser direct writing. The width of superconducting nanowires could be further optimized by adjusting parameters such as laser power, irradiation gap, and delay of points. Compared with electron beam lithography and focused ion beam, to some extent, the nanowires fabrication process based on nano-laser direct writing provides a more efficient and costeffective path for fabricating large-area superconducting circuits and devices.

“…Superconducting elements incorporated into NEMS extend the horizon of this phenomenon, namely through the effects of superconducting phase coherence; see, for example, the following reviews [17,18]. Interplay between electromechanical effects and phase coherence gives new and unusual properties to a number of normal metal/superconducting hybrid junctions [19][20][21].…”

Nanomechanics driven by the superconducting proximity effect

et al. 2022

We consider a nanoelectromechanical weak link composed of a carbon nanotube suspended above a trench in a normal metal electrode and positioned in a gap between two superconducting leads. The nanotube is treated as a movable single-level quantum dot in which the position-dependent superconducting order parameter is induced as a result of Cooper pair tunneling. We show that in such a system, self-sustained bending vibrations can emerge if a bias voltage is applied between normal and superconducting electrodes. The occurrence of this effect crucially depends on the direction of the bias voltage and the relative position of the quantum dot level. We also demonstrate that the nanotube vibrations strongly affect the dc current through the system, a characteristic that can be used for the direct experimental observation of the predicted phenomenon.
