In this work, we first discuss the quality of the DP that we generated for DSG. We then assess the flexibility of DSG by calculating its out-of-plane thermal fluctuations and comparing results with other similar materials. Finally, we use the DP to measure the PT self-diffusion coefficients (D s ) in DSG with a single added proton. Our results indicate that the D s value in DSG was essentially identical to that of SSG at the same temperature.
