The question whether the neutrino is its own antiparticle or not is still not answered. The most feasible way to investigate this is the search for the neutrinoless double beta decay. The nEXO experiment, which is currently under development, will search for this decay. Its baseline concept is a single-phase liquid xenon (LXe) time projection chamber (TPC) filled with about 5 tons of LXe enriched to about 80% Xe-136 as double beta decay nuclide as well as detection material. In order to achieve an excellent energy resolution, a position-resolving, low-noise charge readout as well as very efficient light detection is mandatory. For the purpose of very low background levels, radiopure Silicon Photomultipliers (SiPMs) have to be used to detect the scintillation light of LXe. In this talk, the baseline-concept of the experiment will be presented.
