Abstract

A microscopic theory describing the peak in the temperature dependence of the nonlocal resistance of three-terminal NSN devices is developed. This peak emerges at sufficiently high temperatures as a result of the competition between quasiparticle/charge imbalance and subgap (Andreev) contributions to the conductance matrix. Both the height and the shape of this peak demonstrate the power law dependence on the superconductor thickness L in contrast to the zero-temperature nonlocal resistance, which decays (roughly) exponentially with an increase in L. A similar behavior was observed in recent experiments.
