A linear analytical model of the Josephson DC flip-flop is proposed. The model describes both the Baechtold's and Hebard's flip-flops. The output signal line is treated as either a single inductance or a transmission line with a finite impedance. The

This paper studies an Nb/AlOxNb junction, and the cross-sectional shape of the junction interface and the surface state are observed. It is found that the AlOx film used as the tunnel barrier layer is locally nonuniform and is dependent on the shape
