抄録

We present the first report of observation of photoinduced and electron-beam-induced short-circuit currents across the Al/(lOO)SrTi03/(OOl)YBa2Cu3Oy metal-insulator-superconductor (MIS) structure in the normal state. Observed current flow is an indication of downward band bending of the YBa2Cu30y surface layer at the MIS interface, in accordance with the prediction by Hirano et al. based on its large work-function value (Jpn. J. Appl. Phys. 31 (1992) L1345). The electron-beam-induced current (EBIC) image revealed structural defects at the interface. From this image, diffusion length in the (00l)YBa2Cu3Oy layer was roughly estimated as 0.1 -0.2 pm.
