Surface acoustic wave (SAW) technology has been extensively used in communications and sensing applications. This review summarizes the recent advancement of micro- nanostructured materials enhancing gas performance SAW devices.
Rayleigh surface acoustic wave (SAW) devices based on 128° YX LiNbO3 and ZnO/Si substrates with different resonant frequencies from ∼62 MHz to ∼275 were fabricated characterized. Effects of SAW frequency power microfluidic performance (including streaming, pumping, jetting) investigated. excitation influenced the attenuation length hence energy absorbed by liquid. At higher (e.g., above 100 MHz), dissipated into liquid decays more rapidly much shorter decay lengths. Increasing radio (RF)...
An ultraviolet (UV) sensor based on nanostructured zinc oxide (ZnO)/Si surface acoustic wave (SAW) devices was studied in this paper. The ZnO films sputtered onto Si (100) substrate showed a preferred (0002) orientation and good photoluminescence emission. For an SAW device with wavelength of 64 μm, frequency downshift ∼1.4 kHz observed for the Rayleigh mode under UV light intensity 0.6 mW cm−2, whereas increased to 8.3 after integrating nanorods (NRs) ZnO/Si devices. 20 μm irradiated 25...
Shear horizontal surface acoustic waves (SH-SAWs) have been regarded as good candidates for liquid sensing applications but are inefficient in fluid manipulation due to a minimal coupling between the and waves. However, this letter, vertical jetting function was realized using SH-SAW generated from 36° Y-X LiTaO3 SAW device. The of droplet induced by SH-SAWs observed nearly along direction, aspect ratio beam is proportional applied power before breaking up, which dramatically different those...
The development of an electronic nose (E-nose) for rapid explosive trace detection (ETD) has been extensively studied. However, the extremely low saturated vapor pressure explosives becomes major obstacle E-nose to be applied in practical environments. In this work, we innovatively combine decomposition characteristics nitro when exposed ultraviolet light into gas sensors detecting explosives, and consisting a SnO2/WO3 nanocomposite-based chemiresistive sensor array with artificial neural...
Holographic recording experiments of doubly-doped LiNbO<sub>3</sub>:Fe:Ni crystals were conducted by three kinds different two-color schemes. The results show that the saturation diffraction efficiency, fixing and sensitivity oxidized crystal are higher than those other reported LiNbO<sub>3</sub> crystals. Based on doped energy-band diagram, effect microcosmic optical parameter deep trap center holographic properties is analyzed theoretically. has potential being a new highly efficient...
Dopants in doubly doped lithium niobate crystals are crucial for properties of nonvolatile holographic recording. In our experiments, a series possible congruent LiNbO3:Fe:X (X=Mn, Cu, Rh, Ru, Ni) proposed and investigated The experimental results demonstrate that the dopants with different distances energy band to conduction have recording efficiency. Further analysis approve which moderate energy-band distance can perform both high diffraction efficiency long lifetime. compared show...
An oscillatory characteristic of diffraction is observed during holographic recording period in an oxidized LiNbO<sub>3</sub>:Cr:Cu crystal with 514 nm green light as the and 390 UV sensitizing light. The optimal switching time from step to fixing for high a fixed hologram studied.
