We present the fabrication of 570-$\ensuremath{\mu}\mathrm{m}$-thick millimeter-sized soda-lime-silicate float-glass blocks with a 1-$\ensuremath{\mu}\mathrm{m}$-thick $\mathrm{Al}\mathrm{N}$ thin-film piezoelectric transducer sandwiched between thin

We report a transduction optimization method of piezo-based MEMS structures using segmentation of the excitation electrodes. Optimal transduction is achieved by matching the electric field distribution to the polarization distribution including the d

Ultrathin aluminum nitride (AlN) films are of great interest for integration into nanoelectromechanical systems for actuation and sensing. Given the direct relationship between crystallographic texture and piezoelectric response, x-ray diffraction ha

A measurement setup for the detailed study of the transverse piezoelectric coefficient ${e} \mathbf {{}_{31,f}} $ in the converse (actuator) mode was developed. It allows the assessment of the piezoelectric stress in thin films on silicon cantilevers

A novel type of hybrid resonator based on BAW transformation into SAW in a ridged layered structure was fabricated and characterized. Bulk waves are excited by micromachined piezoelectric AlScN pillars located on the non-piezoelectric Si and sapphire

Sputter deposited Al(1-x)ScxN thin films with a Sc content from x = 0 to 43 at% are investigated by electron microscopy in order to study and explain the formation and growth of abnormally oriented grains (AOG). It is found that the latter did not nu

There is a need for sensors capable operating at temperatures above 1000 degrees C. We describe an innovative sensor that might achieve this goal. The sensor comprises two main elements: a thermocouple and a surface acoustic wave (SAW) strain sensor.

Currently, large efforts are going on to scale up PZT thin film processes for large volume MEMS fabrication. It is critical to complete the scaling up with optimized film properties. In this work we report about microstructural control and piezoelect

Piezoelectric wurtzite ScxAl1-xN (x = 0, 0.1, 0.2, 0.3) thin films were epitaxially grown by reactive magnetron co-sputtering from elemental Sc and Al targets. Al2O3(0001) wafers with TiN(111) seed and electrode layers were used as substrates. X-ray
