Low-Temperature Processing of PZT-PMN Thin Film by Sol-Gel Casting

Processing Sol-gel Pzt Thin Films for Microactuators

Sol-gel derived lead zirconate titanate (PZT) thin films are being investigated for micromechanical applications. A synthesis technique which involves the spin coating of several thin layers followed by rapid thermal annealing to crystallize the perovskite phase and repetition to achieve thicker films is described. Methods of improving the PZT-PZT interfaces between subsequently annealed layers...

Sol‐gel silicate thin‐film electronic properties

BaFe12O19 thin film grown by an aqueous sol-gel process

In this communication we present a new sol–gel route to obtain high quality BaFe12O19 thin films. X-ray analysis confirmed the crystal structure with a crystal size of 32 nm. Atomic force microscopy images determined the film thickness to be around 250 nm and a roughness factor of less than 40 nm where the grain size averaged around 150 nm. SQUID magnetometer data shows a magnetic behavior simi...

Thin-film silica sol-gel coatings for neural microelectrodes.

The reactive tissue response of the brain to chronically implanted materials remains a formidable obstacle to stable recording from implanted microelectrodes. One approach to mitigate this response is to apply a bioactive coating in the form of an ultra-porous silica sol-gel, which can be engineered to improve biocompatibility and to enable local drug delivery. The first step in establishing th...
