Bridging the gap between single crystals and ceramics.(ELECTRONICS)
Advanced Ceramics Report, August, 2005
Scientists at Rutgers University, USA, have developed novel piezoelectric materials that mimic the performance of traditionally fabricated crystalline wafers, without the time and expense of growing crystals in a molten mixture.
The technique could see the development of single-crystal piezoelectrics in sizes and shapes that are impossible using standard methods.
The research was led by Dr Richard Riman, a professor of ceramic and materials engineering at Rutgers, with collaboration from Ceramare Corp and University of California at Berkeley, both also USA.
Riman and his colleagues conducted their research using lead zirconate titanate (PZT), a piezoelectric used in motion sensors and electrical capacitors, amongst other applications. It is...
