Analysis of GaN Based SAW Resonators including FEM Modeling
This paper proposes an analysis of two types of Surface Acoustic Wave (SAW) resonators composed of interdigital transducers (IDT) of 200 nm wide on GaN/Si devoted for GHz applications. Two finite element (FEM) models for basic periodic cells are given to demonstrate de characteristics of the resonators at different resonance frequencies. E-beam lithographical techniques have been used for the I...
متن کاملDevelopment and Experimental Analysis of Piezoelectric Optical Scanner Based on FEM and Laser Holography
Piezoelectric optical scanner is developed for multi-coordinate control of optical laser beam. Such type of optomicro-mechanical systems can be used for accurate angular or linear deflection of optical elements in various optomechanical and optoelectronic systems. The operating principle of these devices is based on piezoelectric effect and on conversion of high-frequency multi-dimensional mech...
متن کاملPredicting Magnetoelectric Coupling in Layered and Graded Composites
Magnetoelectric (ME) interaction in magnetostrictive-piezoelectric multiferroic structures consists in inducing the electric field across the structure in an applied magnetic field and is a product property of magnetostriction and piezoelectricity in components. ME voltage coefficient that is the ratio of induced electric field to applied magnetic field is the key parameter of ME coupling stren...
متن کاملMetal piezoelectric semiconductor field effect transistors for piezoelectric strain sensors
In this letter, we examine the potential of a functional device that can have good transistor and stress sensor properties. The device examined is based on the use of a thin oxide with high piezoelectric coefficients under the gate region. Channel charge and current are controlled by gate voltage or by stress. We examine the performance of two classes of heterostructures that are important semi...
متن کاملSimulation of SAW Humidity Sensors Based on (112¯0)ZnO/R-Sapphire Structures
The characteristics of two types of surface acoustic waves SAWs (Rayleigh waves and Love waves) propagating in bilayered structures of ( 11 2 ¯ 0 ) ZnO/R-sapphire are simulated by a finite element method (FEM) model, in which both SAWs have crossed propagation directions. Furthermore, based on the bilayered structures, the frequency responses of Rayleigh wave and Love wave humidity sensors are ...
