Superconductor with a lack of inversion symmetry in their crystal structure have recently been proposed as systems hosting an unconventional and other topologically nontrivial superconducting states, which could pave their application for the fabrication of novel devices for superconducting spintronics and quantum computing. Moved by these motivations, we have investigated the transport and spectroscopic properties of the non-centrosymmetric superconductor Nb0.18Re0.82 down to the 2D limit. Hall transport measurements in the normal state and tunnelling spectroscopic experiments reveal the emergence of a complex physical behaviour, which suggests the existence of a superconducting order parameter with unconventional properties.
