Notes:
p-type semiconducting perovskites Sm1-xAxFe1-yByO3 (A=La, Sr, x=0, 10, 20 at%, B=Cr,Co, Mn, y=0, 10, 20 at%) were synthesised via the polyol method. X-ray diffraction (XRD) andscanning electron microscopy (SEM) were used to confirm the structure and morphology of thematerials. Thick films of the materials prepared together with surface doped SmFeO3 (with Au, Ce,Ir, Pd, Pt, Rh, Ru) samples were electrically characterised using high throughput impedancespectroscopy (HT-IS). The gas sensing behaviour was tested at temperatures ranging from 200 to500°C. For La and Cr doping a model describing a correlation between the (M-O) binding energyand the sensing properties was verified
