In this study, we show that it exhibits high Seebeck coefficients 200 - 300 $\\mu$V/K in its cubic crystalline phase ($\\it{c}$-GST) at remarkably high $\\it{p}$-type doping levels of $\\sim$ 1$\\times$10$^{19}$ - 6$\\times$10$^{19}$ cm$^{-3}$ at room temperature. More importantly, at low temperature (T = 200 K), the Seebeck coefficient was found to exceed 200 $\\mu$V/K for a doping range 1$\\times$10$^{19}$ - 3.5$\\times$10$^{19}$ cm$^{-3}$.
