Whatmore RW, 2000, Ferroelectrics, microsystems and nanotechnology, Pages: 39-43, ISSN: 0963-3308
The concepts of ferroelectrics, microsystems, and nanotechnology are discussed. Ferroelectric materials possess many useful properties which are widely exploited in electronic devices, and are also useful for microsystem devices and nanotechnology. Microsystems Technology (MST) has many things to offer to nanotechnology such as in the field of scanning probe devices integrated onto silicon chips. There are also some aspects of MST devices which could come into the nanotechnology range such as quantum well semiconductor layers.
Kirby P, Su QX, Komuro E, et al., 2000, High frequency thin film ferroelectric acoustic resonators, Pages: 5-7, ISSN: 0963-3308
The features and benefits of thin films bulk acoustic resonators (FBAR) are discussed. The FBAR are best suited for future mobile communication system as they are compact, have low-loss and are largely compatible with the existing high frequency Si/GaAs IC processing. A FBAR is a resonant piezoelectric device similar to the quartz resonators, which consists of piezoelectric layer sandwich between two electrodes. Larger 3 dB bandwidths can be obtained from PZT FBAR filters due to the larger electromechanical coupling coefficient for PZT.

The term "Nanotechnology" was first coined by Taniguchi in 1974 to describe the precision manufacture of mechanical parts with finishes and tolerances in the nanometer range. However, the term has now expanded in its meaning to cover the fabrication and exploitation of entities (materials, devices etc) in which there is a dimension of less than 100nm which is critical to performance or behaviour. It covers a wide range of activities from ultra-precision engineering and fine-line lithography through nanostructured materials to the manipulation of biological molecules. There is a strong overlap with the subject of microsystems technology (MST), whereby systems incorporating sensing, signal processing, actuation and communications are integrated into a single microengineered package. Ferroelectric materials offer a wide range of properties which can be used in microsystems and nanotechnology, particularly the pyroelectric effect for thermal infra-red detection and imaging and the piezoelectric effect for sensors (sound, acceleration etc), and for actuators (e.g. cantilevers and motors). Ultimate applications could lie in the fields of nanoscale fabrication and information storage. The potential for ferroelectric thin films to contribute to these fields is discussed, and problems reviewed, especially from the aspect of materials and process integration. Specific examples of the factors critical to the growth and behaviour of thin films at low temperature by sol gel are discussed.
