In the present letter, Pd/Al₂O₃/MoS₂/ITO MISM UV photodetector structure is proposed and analyzed. For the proposed photodetector, responsivity is 488 A/W, detectivity is $8.22\times 10 ^{12}$ Jones and external quantum efficiency (EQE) is $1.9\times 10 ^{5}$ %, at wavelength 308nm, 1V bias and light intensity $13.6~\mu \text{W}$ /cm². Thus, proposed MISM photodetector device gives significant performance improvement over other UV photodetectors.
