EnglishJosephson-junction devices such as suitably designed nanoSQUIDs can provide a sensing element for micro and nanoelectronics. In this paper, the properties of such device must be tailored in order to have an optimal response. In particular, it relates its temperature stability, and a comparatively weak dependence of the critical supercurrent Ic on temperature Tin the working range. To realize it, a concave upward Ic-versus-T curve is required. The aim of this paper was to study conditions when such temperature dependence can be realized in four-layered S/N-I-S Josephson junctions, mantaining the overdamped behavior. We show how the shape of the Ic-versus-T dependence can provide important information about the strength of the S/N proximity coupling.

| Abstract: | Josephson-junction devices such as suitably designed nanoSQUIDs can provide a sensing element for... micro and nanoelectronics. In this paper, the properties of such device must be tailored in order to have an optimal response. In particular, it relates its temperature stability, and a comparatively weak dependence of the critical supercurrent Ic on temperature Tin the working range. To realize it, a concave upward Ic-versus-T curve is required. The aim of this paper was to study conditions when such temperature dependence can be realized in four-layered S/N-I-S Josephson junctions, mantaining the overdamped behavior. We show how the shape of the Ic-versus-T dependence can provide important information about the strength of the S/N proximity coupling. | |
