## Description

- description: Nonreciprocal transport refers to charge transfer processes that are
    sensitive to the bias polarity. Until re- cently, nonreciprocal transport was
    studied only in dissipative systems, where the nonreciprocal quantity is the resistance.
    Recent experiments have, however, demonstrated nonreciprocal supercurrent leading
    to the observa- tion of a supercurrent diode effect in Rashba superconductors,
    opening the vision of dissipationless electronics. Here we report on supercurrent
    diode effect in NbSe2 nanowires obtained by patterning NbSe2 flakes with odd layer
    number. The observed rectification efficiency in NbSe2 can be as large as 50%,
    almost an order of magni- tude larger than the efficiency of devices based on
    Rashba superconductors. In agreement with recent theory for superconducting transition
    metal dichalcogenides, we show that the effect is driven by the out-of-plane magnetic
    field component. Remarkably, we find that the effect becomes field-asymmetric
    in the presence of an additional in-plane field component transverse to the current
    direction. Supercurrent anisotropy offers a further degree of freedom in designing
    superconducting power electronics with the high degree of integrability offered
    by van der Waals materials.
