Electro-Optical Properties of Sputtered Calcium Lead Titanate Thin Films for Pyroelectric Detection [PDF]

open access: yesMicromachines, 2020
We report the deposition and characterization of calcium lead titanate (PCT) thin films for pyroelectric detectors. PCT films of thicknesses ranging from ~250 to 400 nm were deposited on both silicon and Si/SiN/Ti/Au substrates at 13 mTorr pressure by ...
