Abstract

A microbolometer may include a sensitive material based on vanadium oxide (VOx) with an additional chemical element such as boron (B), but excluding nitrogen (N), the sensitive material wherein the sensitive material (i) is amorphous, (ii) has an electrical resistivity at ambient temperature in a range of from 1 to 30 Ω·cm, (ii) has a homogeneous chemical composition, and (iv) has an amount of boron, defined as a ratio of a number of boron to vanadium atoms to that of vanadium, at least equal to 0.086.
