The development of wireless and mobile communication in the last decade led to the elaboration of new components based on thin films with continually increasing performance and reduced fabrication cost. A fundamental element for mobile communication is the ...
Pb(Zr, Ti)O-3 (PZT) is an interesting material for bulk acoustic wave resonator applications due to its high electromechanical coupling constant, which would enable fabrication of large bandwidth frequency filters. The major challenge of the PZT solid solu ...
The progress in the technology of microelectronic devices has led to a strong miniaturization and high performance for circuits and systems, enabling modern applications such as mobile computing and communications. Today, remaining "off-chip" components th ...
We report a study on the interaction of the extracellular domain of trans-membrane proteins N-cadherin and Ll with nitrilotriacetic acid (NTA)-terminated self-assembled monolayers (SAMs) grown on silver and gold surfaces. Quartz crystal microbalance (QCM) ...
In this paper we report work on a modified potassium sodium niobate composition that has the potential to replace PZT for piezoelectric thin film applications. Pulsed laser depositions were undertaken on platinised Si substrates. The resultant films were f ...
The piezoelectric properties of tetragonal BaTiO3 (BTO) crystals with a high density of 90° twin domain boundaries were experimentally investigated by Wada and Tsurumi (2004 Br. Ceram. Trans. 103 93). These crystals with engineered dense domain structures ...
Today's consumer electronics based on a large variety of time-keeping and frequency reference applications is based on quartz-crystal oscillators, because of their excellent performances in terms of quality factor, thermal and frequency stability. However, ...
Piezoelectric thin films have existing and promising new applications in microwave filter technologies. The final performance depends on many parameters, and very specifically on the materials properties of each involved material. In this article, material ...
The piezoelectric properties of 31-mode resonators of lead zirconate titanate ceramics under hydrostatic pressure from 0.1 to 325MPa were evaluated by a fitting method, in which mechanical loss was taken into account. Our results based on the fitting metho ...
