An optimized Graphene/4H-SiC/Graphene MSM UV-photodetector operating in a wide range of temperature

•An optimized IGE/p-4H-SiC MSM UV PD operating in a wide range of temperature has been analytically investigated.•An optoelectronic analytical model that considers different carrier loss mechanisms has been developed.•A MOGA-based optimization approach has been successfully implemented in the context of our investigation.•The optimized design outperforms considerably the conventional designs.•Our results confirm the excellent ability of the suggested Graphene electrodes system for decreasing the unwanted shadowing effect.
