The microstructure of nonpolar heteroepitaxial wurtzite films (GaN and ZnO-based) is dominated by the presence of planar basal stacking faults (BSFs). In this paper, transmission electron microscopy studies of both GaN and ZnO nonpolar films oriented eithe ...
Static flexoelectric effect in a finite sample of a solid is addressed in terms of phenomenological theory for the case of a thin plate subjected to bending. It has been shown that despite an explicit asymmetry inherent to the bulk constitutive electromech ...
Spin wave excitations in dipolarly coupled nanodisks from permalloy are investigated. We address, both, onedimensional (1D) chains and two-dimensional (2D) arrays consisting of nanodisks of different diameter. An out-of-plane magnetic field allows us to in ...
The use of acoustic resonators for sensors application has opened a new branch in research and applications of piezoelectric materials and devices. The first generation of such sensors is constituted by the quartz crystal microbalance (QCM) based on AT-cut ...
We study the spin dynamics in arrays of densely packed submicron Ni80Fe20 wires which form one-dimensional magnonic crystals. They are subject to an in-plane magnetic field H being collinear with the wires. In the case when neighboring wires are magnetized ...
We address the problem of microphone location calibration from a sparse coding perspective where the sensor positions are approximated over a discretized grid. We characterize the microphone signals as a sparse vector represented over a codebook of multi-c ...
Due to low power operation, intrinsic integrability and compatibility with CMOS processing, aluminum nitride (AlN) piezoelectric (PZE) microcantilevers are a very attractive paradigm for resonant gas sensing. In this paper, we theoretically investigate the ...
The manufacture and characterisation of an elastic dipole antenna that is reversibly deformable and stretchable is described. The metallisation technique of depositing sub-micron-thick gold (Au) film on pillar patterned elastomer polydimethylsiloxane has b ...
We address the problem of microphone location cali- bration where the sensor positions have a sparse spatial approximation on a discretized grid. We characterize the microphone signals as a sparse vector represented over a codebook of multi-channel signals ...
Inkjet printed interdigitated transducers have been produced on flexible substrates and optimized for gas sensing applications by improving the sintering conditions and employing additional passivation procedures, like electroplating with Ni or whole trans ...
