The significantly enhanced superconducting transition temperature ($T_c$) ofan FeSe monolayer on SrTiO$_3$(001) substrate has attracted extensive attentionin recent years. Here, based on first-principles electronic structurecalculations, we propose another candidate substrate LaO(001) for the epitaxialgrowth of FeSe monolayer to realize superconductivity. Our calculations showthat for the optimal adsorption structure of FeSe monolayer on LaO(001), thestripe antiferromagnetic state and the dimer antiferromagnetic state are almostenergetically degenerate, indicating the existence of strong magneticfluctuation that is beneficial to the appearance of superconductivity.According to the Bader charge analysis, the calculated electron doping from theLaO substrate to the FeSe monolayer is about 0.18 electrons per Fe atom, evenlarger than that in case of FeSe/SrTiO$_3$(001). Since LaO was also reported tobe a superconductor with $T_c$ ~ 5 K, it may have a superconducting proximityeffect on the epitaxial FeSe film and vice versa. These results suggest thatLaO would be an interesting substrate to study the interface-relatedsuperconductivity.
