H–T phase diagram for the graphene-tin nanoislands array hybrid. The Tpeak1 (black square), Tpeak2 (red pink circle), HTCR (black solid line), and LTCR (red pink solid line) separate the superconductivity region (dρ/dT > 0) and the weakly localizing metal region (dρ/dT < 0). TTAFF points, which correspond to the black arrows in the Arrhenius plot (Supplementary Figure 15), define the boundary between the thermal activation region and the quantum tunneling vortex region. Intra Island SC and Inter Island SC denote the intra-tin nanoisland superconductivity and the inter-tin nanoisland superconductivity, respectively
