“…However, the poor electrical conductivity limits their electrochemical performance. In the recent years, Ni-Fe oxyhydroxide (Ni 1-x Fe x OOH) [15][16][17] and NiFe layered double hydroxide (LDH) [18][19][20][21] is intensively studied for OER. Trotochaud et al reported that, loading of Fe could not only improve the conductivity, but also modify the electronic structure of NiOOH making it highly reactive for electrochemical performance.…”

“…It has negative temperature coefficients of elastic and piezoelectric constants [34]. SiO 2 is an intermediate passive layer used in the lithiumniobate-on-insulator (LNOI) technology [39]. SiO 2 is usually used for temperature compensation as it has positive temperature coefficients of elastic constants [34].…”

In this article, near-zero drift and high electromechanical coupling acoustic resonators have been designed and demonstrated. The acoustic resonator is based on Lamb acoustic waves in a bimorph composed of lithium niobate on silicon dioxide. Our approach breaks through a performance boundary in conventional Lamb-wave resonators by introducing the bimorph while operating at higher order resonant modes. This enables the resonator to achieve frequency scalability, a low-temperature coefficient of frequency, and high electromechanical coupling altogether. The electromechanical coupling and temperature coefficient of the resonator were analytically optimized for the A 3 mode through adjusting the thicknesses of different materials in the bimorph. Resonators with different dimensions and stack thickness were fabricated and measured, resulting in a temperature coefficient of frequency ranging from −17.6 to −1.1 ppm/ • C, high electromechanical coupling ranging from 13.4% to 18%, and quality factors up to 800 at 3.5 GHz. The achieved specifications are adequate for fifth-generation (5G) sub-6-GHz frequency bands n77 and n78. Index Terms-Acoustic resonators, fifth generation (5G), lithium niobate on insulator (LNOI), low-temperature coefficient of frequency (TCF), microelectromechanical systems (MEMS), new radio (NR), piezoelectricity. I. INTRODUCTION T HE fifth-generation mobile network (5G) is a global wireless standard advancing the prevalent connectivity between people, machines, and devices [1], [2]. The third-generation partnership project (3GPP), a collective project partnership of mobile system manufacturers, has played a critical role in the development and deployment of the 5G standard [1]. Specifically, 5G new radio (NR) uses modulation schemes, waveforms, and access technologies, enabling increased data rates, coverage, reliability, capacity, and low latency [2]. 5G is driven by consumers and industrial trends, such as enhanced mobile broadband (eMBB), Internet of Things (IoT), smart vehicles, and healthcare/critical Manuscript
