Noble Liquid Time Projection Chambers are ubiquitously used in the field of rare events searches such neutrinoless double beta decay or dark matter. A detailed understanding of light and charge transport in liquid xenon or liquid argon is of the utmost importance when modeling the performance of these experiments. In this talk I will present the design and physics reach of the proposed nEXO experiment, searching for the neutrinoless double beta decay of Xe-136 at the 10^28 year half-life sensitivity using 5 tonnes of liquid xenon. The energy resolution is one of the key parameter for achieving the projected sensitivity, requiring highly efficient light and charge detection systems. I will show results towards modeling the electron transport in the presence of electro-negative contaminants in liquid xenon and comprehensive results for the characterization and simulation of the light response of the Silicon Photomultipliers used in nEXO.
