Abstract

This paper proposes an uncooled infrared detector based on a heterostructure comprising Ba_0.7Sr_0.3TiO₃ (BST) ceramic and graphene. The relationship between heterojunction current and ambient temperature was determined to further analyze the effect of BST phase transition on the graphene resistance. The current at 0.1 V increased by 0.3% and 4% as the temperature was increased to 27 and 31 °C, respectively. Thus, the rate of change within the phase transition temperature range was 0.9%/°C. These insights serve as a foundation for the development of graphene/ferroelectric heterostructures for application in uncooled infrared detectors.
