Abstract:

The objectives of the contract were to prepare thin films of PbTiO3, measure their properties and determine their performance for pyroelectric detection of infrared and millimeter-wave 94 GHz radiation. Thin films of PbTiO3 were deposited on silicon microstructures consisting of Si3N4 membranes over etch pits in silicon substrates. Upper and lower Pt electrodes formed electrical contacts to the PbTiO3 pyroelectric films. Aluminum metallizations in the form of full-wave and half-wave dipoles contacting the PbTiO3 pixels were developed for detection of 94 GHz radiation. Infrared detection was by direct absorption in the PbTiO3 pixel. Two process runs incorporating single pixels and linear arrays were carried out and the results described....
