Temporal response of a high-T c superconducting field effect transistor

Abstract: YBa2Cu3O7−x/SrTiO3/Au multilayer systems have been prepared in situ by pulsed laser deposition onto (100) SrTiO3 substrates. An electric field controlled device was patterned by suitable metal masks applied successively during the deposition process. The switching time of the superconducting source-drain channel has been studied at T=4.2 K applying rectangular pulses to the gate electrode. We find that the source-drain voltage follows the gate voltage variation in accordance with the RC time constant of the de… Show more

“…The second scenario involves an electric field-driven redistribution of the oxygen atoms in the basal planes of YBCO, as proposed already in the 90s. 29 This possibility was discarded for solid-state field effect devices due their fast response, 30 yet, in our case, the huge electric field applied by the EDL and the slow response time of our device are consistent with Ref. 29.…”

“…Following a theory based on field-driven oxygen ordering in the CuO chains of YBCO, 27 the field-induced formation of an oxygen superlattice structure, like ortho I and ortho II, is in principle, conceivable. But the model has elicited concern from the experimental side 14,15 and the plateaulike property of Fig. 5͑a͒ may have a different unknown origin.…”

“…Details of the manufacture of the device by using a metal mask patterning technique are described elsewhere. 15,16 Briefly, an ultrathin, 5-to 10-nmthick c-axis oriented YBCO channel is patterned between two 120-nm-thick YBCO source ͑S͒ and drain (D) electrodes. Due to the high oxygen pressure of 0.25 mbar during deposition that causes a nonballistic flight of the ablated material and the metal mask just pending over the substrate, the edges of the electrodes are smeared out leading to a thickness gradient in the channel region close to the electrodes.…”
