Query: Gate control of superconductivity in mesoscopic all-metallic devices   It was recently demonstrated the possibility to tune, through the application
of a control gate voltage, the superconducting properties of mesoscopic devices
based on Bardeen-Cooper-Schrieffer metals. In spite of the several experimental
evidence obtained on different materials and geometries, a description of the
microscopic mechanism at the basis of such unconventional effect has not been
provided yet. This work discusses the technological potential of gate control
of superconductivity in metallic superconductors and revises the experimental
results which provide information regarding a possible thermal origin of the
effect: in the first place, we review experiments performed on high critical
temperature elemental superconductors (niobium and vanadium) and show how
devices based on these materials can be exploited to realize basic electronic
tools such as, e. g., a half-wave rectifier. In a second part, we discuss the
origin of the gating effect by showing the gate-driven suppression of the
supercurrent in a suspended titanium wire and by providing a comparison between
thermal and electric switching current probability distributions. Furthermore,
we discuss the cold field-emission of electrons from the gate by means of
finite element simulations and compare the results with experimental data.
Finally, the presented data provide a strong indication regarding the
unlikelihood of thermal origin of the gating effect.
