Bilayer Moir\'e structures are a highly tunable laboratory to investigate thephysics of strongly correlated electron systems. Moir\'e transition metaldichalcogenides at low-energies, in particular, are believed to be described bya single narrow band Hubbard model on a triangular lattice with spin-orbitcoupling. Motivated by recent experimental evidence for superconductivity intwisted bilayer materials, we investigate the possible superconducting pairingsin a two-dimensional single band Rashba-Hubbard model. Using a random-phaseapproximation in the presence of nearest and next-nearest neighbor hopping, weanalyze the structure of spin fluctuations and the symmetry of thesuperconducting gap function. We show that Rashba spin-orbit coupling favorsferromagnetic fluctuations which strengthen triplet superconductivity. Ifparity is violated due to the absence of spatial inversion symmetry, singlet(d-wave) and triplet (p-wave) channels of superconductivity will be mixed.Moreover, we show that time-reversal symmetry can be spontaneously brokenleading to a chiral superconducting state. Finally, we consider quasiparticleinterference as a possible experimental technique to observe thesuperconducting gap symmetry.
