Mp. Bruijn et al., NB-BASED SUPERCONDUCTING TUNNEL-JUNCTIONS FOR X-RAY SPECTROSCOPY - TAOX AND ALOX TUNNELBARRIERS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 370(1), 1996, pp. 101-103
Results are presented of an optimization study of TaOx-tunnelbarriers
in superconducting tunneljunctions for X-ray spectroscopy. The propert
ies did not satisfy the critical demands. A comparison is made with fi
rst results on AlOx-barriers made with the same processing setup. AFM
and TEM were used in studies of interface roughness.
