The structural accuracy, reflected in lattice parameters and unit cell volume, closely corresponds to previously reported data. FrGeI<sub>3</sub> and FrSnI<sub>3</sub> exhibited direct electronic band gaps of 0.65 eV and 0.46 eV with GGA-PBE functional, respectively, indicating their semiconducting nature at 0 GPa.

Using XRD and XPS, the structural and chemical features of MgO are assessed, confirming that the MgO was deposited on un-InP. The current-voltage (log(I)-V) features were measured for the SC and Au/MgO/un-InP metal/insulator/semiconductor (MIS)-type Schottky contact. The MIS contact revealed an excellent rectification behavior as compared to the SC. The calculated barrier height (Φ<sub>b</sub>) was higher for the MIS contact (0.61 eV) than the SC (0.52 eV), which implies that the MgO interlayer influences the Φ<sub>b</sub> of the SC. The Φ<sub>b</sub> was also estimated using the Cheung's, Mikhelashvili and Norde procedures, the values are similar, indicating their stability and reliability. The acquired interface state density (N<sub>SS</sub>) of the MIS contact was less than the SC, proving that the MgO interlayer reduced the N<sub>SS</sub>. The ohmic behavior was observed in the lower bias region for the SC and MIS contacts, while the trap-free space-charge-limited current (SCLC) was noted in the moderate and upper bias regions of the MIS contact under forward bias. Poole-Frenkel emission (PFE) governs at a lower bias, while Schottky emission (SE) dominates at the upper bias of SC and MIS contacts under reverse bias.
