“…Various research groups have investigated thinfilm based MIM diodes for IR detection [1,3,4,[8][9][10][11] and found that MIM diodes with high enough work function difference electrodes exhibit non-linear current-voltage (I-V) behaviour that can produce rectification. They have been fabricated with a wide variety of material combinations like, Al-Al 2 O 3 -Al [12], Cr-CrO-Au [9,13], Al-Al 2 O 3 -Ag [14], Nb-NbOx-Au [13], NiNiO-Au, Ag, Ni, Pt, [4,11,15,16]. In this work Ni-NiO-Cr MIM diodes were fabricated on a Si substrate using standard IC processing technology to exhibit a more pronounced level of non-linearity and asymmetry.…”
