For all samples in this regime, the resistive transition occurs at $T_{c} \\approx 65 \\pm 25 \\ mK$. We observe a zero resistance state for $\\textit{n}$ as low as $1.03 \\times10^{17}cm^{-3}$, and a partial resistive transition for $\\textit{n} = 3.85 \\times10^{16}cm^{-3}$. We observe low critical current densities, relatively high and isotropic upper critical fields, and an absence of diamagnetic screening in these samples.
