Scalable fabrication of a hybrid field-effect and acousto-electric device by direct growth of monolayer MoS2/LiNbO3

Lithium niobate is the archetypical ferroelectric material and the substrate of choice for numerous applications including surface acoustic wave radio frequencies devices and integrated optics. It offers a unique combination of substantial piezoelectric and birefringent properties, yet its lack of optical activity and semiconducting transport hamper application in optoelectronics. Here we fabri...

بررسی کوپلینگ پیزوالکتریکی و آنیزتروپی بر انتشار امواج صوتی در بلوره صوتی لیتیوم نیوباته

The acoustic wave velocity depends on elasticity and density at most materials, but because of anisotropy and especially piezoelectric coupling effect, the acoustic wave propagation at piezoelectric based crystalloacoustic materials, is an applied and challenging problem. In this paper, using modified Christoffel's equation based on group velocity concept, the effect of anisotropy and piezoelec...

Propagation Characteristics of Surface Acoustic Waves in AlN/128°Y-X LiNbO3 Structures

In this study, propagation characteristics of surface acoustic waves in a layered piezoelectric structure (AlN/128°Y-X LiNbO3) are investigated. The phase velocity and coupling coefficient of the layered structure with interdigital transducers and/or metal thin films deposited at various interfaces will be calculated numerically. The effects of the polarity of 128°Y-X LiNbO3 on SAW characterist...

Surface Acoustic Wave Devices for Wireless Strain Measurement

Strain monitoring is a nondestructive inspection method that can reveal the redistribution of internal forces, or the presence of anomalous loadings, in structures. Surface acoustic wave (SAW) devices are small, robust, inexpensive solid-state components in which a wave propagates along the surface of a piezoelectric material, and such devices are used in large numbers commercially as delay dev...
