Lead scandium tantalate (PST) thin films have been deposited on a platinized silicon substrate with and without a buffer layer of MgO at the temperature of 525°C. It was found that PST films on the substrate without a buffer layer were strongly (1 1

Sputtered thin films of perovskite-structured ferroelectric Pb(Sc1/2, Ta11/2)O3, (PST), produced using near stoichiometric ratios of the constituent metals require a post-deposition anneal temperature of 900[ddot]C to promote crystallization of the f

Lead scandium tantalate (PST) thin films sputtered onto sapphire substrates have been studied by using transmission electron microscopy. Samples in transverse section were used to characterize the microstructure of the thin films as a function of dis

Thin films of lead scandium tantalate have been prepared by rf magnetron sputtering. The process involves two deposition steps. In the first, scandium tantalate is sputtered onto a heated sapphire substrate using a metal Sc/Ta target. This film is an

The basic technique for the manufacture of laser reticulated IR detector arrays, by means of KOH assisted UV laser etching, has been described in earlier work in which the individual elements of the array are reticulated by a set of orthogonal groove

Recently attention has been given to the solid state readout of large pyroelectric arrays, particularly the interfacing of two dimensional arrays with a silicon charge coupled device (CCD). The paper gives the theoretical analysis of the electrical a

The performance of a television camera using the one-inch pyroelectric vidicon has been measured. The results are compared with an analysis which attempts to identify the factors limiting the performance of the system. Two modes of operation are cons
