Abstract

The pyroelectric coefficient and pyroelectric infrared response in the sol-gel derived Ba_0.8Sr_0.2TiO₃ thin films have been studied for possible infrared detector applications. The measured pyroelectric coefficient is larger than 3.1 × 10^-4C/m² K at temperatures ranging from 10 to 26 °C and reaches the maximum value of 4.1 × 10^-4 C/m² K at 16 °C. The infrared detectivity of 4.6 × 10^-6 cm Hz^1/2 W^-1 has been obtained at 19 °C and 10 Hz in the Ba_0.8Sr_0.2TiO₃ films deposited on thick (500 μm) platinum coated silicon substrates. The better infrared response can be expected by the improvement in the thermal isolation of pyroelectric element and the electrode materials.
