Abstract

AbstractRelaxor‐based ferroelectric single crystals, such as (1 − x)Pb(Mg1/3Nb2/3)O3xPbTiO3 (PMNxPT, or PMNT) single crystals, exhibit large pyroelectric response, low thermal diffusivity, and high temperature stability. To fabricate high performance infrared detectors with relaxor‐based single crystals, the related readout circuit was investigated to increase signal‐to‐noise ratio, and 8 × 1 CMOS readout circuit is fabricated to gain very weak current, which provides a solution for uncooled large focal plane arrays devices based on relaxor‐based single crystals.
