摘要：
Nb/Al/AlOx/Nb junctions have been shown to be effective x-ray detectors that are robust to thermal cycling. We compare results from two junctions, one with a fine-grained base-layer electrode and counterelectrode and the other with an epitaxial base-layer electrode and a fine-grained counterelectrode. For a 6 keV x-ray, at 0.4 K, the epitaxial sample had a FWHM resolution of 157 eV and the fine-grained junction had a FWHM resolution of 300 eV. The differences between the junctions will be discussed.
