✦ Synopsis

06 Electrical power supply and utilization (scientific, technical) the polarization potential is built up at the interface. The high dielectric constant of ferroelectric films also enhances dipole polarization, substantially improving the Hz gas-induced polarization potential. The results obtained from this experiment reveal the possibility of fabricating largescale, silicon-based ferroelectric thin film gas sensors and related electronic devices, even though research is still in its early stages. 99lO2580

New hydrated cobalt-substituted nickel hydroxides were prepared and characterized. These materials were obtained either by precipitation (a) or by the "chimie douce" technique (a\* and a'). Cobalt generally stays in the trivalent state. In contrast with the aco~+ phases, the aco,\* phases are stable
