Temperature Stability of Surface Acoustic Wave Resonators on In-Plane Rotated 33° Y-Cut Quartz

Abstract

The magnetic response of a type II superconductor lo an applied magnetic field is described by solving the Bean model and viscous flux flow equations simultaneously. Two analytical solutions are presented, which detail the flux distribution within the superconductor induced by a sawtooth-like applied magnetic field. The resultant hysteresis loops show features which depend strongly on the 'sharpness' of the sawtooth waveform. A s expected the magnetic hysteresis losses increase with frequency, reflecting t h e viscous nature of t h e flux flow. In the zero frequency limit. as the velocity of flux flow approaches zero. the usual Bean result is obtained.

Mercury Sorption and Desorption on Gold: A Comparative Analysis of Surface Acoustic Wave and Quartz Crystal Microbalance-Based Sensors

“…The SAW device used in this study was fabricated by patterning Au electrodes on a ST-cut quartz substrate. ST-cut quartz is a commonly used substrate for fabricating SAW-based devices because of its relatively higher temperature stability at 20–70 °C when compared to materials such as XY-lithium niobate or YX-lithium tantalate . First, 20 and 30 nm titanium (Ti) and nickel (Ni) adhesion layers were deposited on top of an ST-quartz substrate (15 mm in length, 9 mm in width and 500 μm in thickness), respectively.…”

“…12,13) Therefore, in this section, we report the temperature dependency of the obtained five types of routes. The LiNbO 3 ball and interdigital electrode plate were set in a vacuum chamber.…”

Highly sensitive ultraviolet sensor based on ZnO nanorod film deposited on ST-cut quartz surface acoustic wave devices

“…Among the commonly used piezoelectric substrates, ST-cut quartz has the lowest temperature coefficient of frequency (TCF) [13,14], thus is an ideal substrate for fabricating SAW devices.…”
