Resonant Magnetometer for Ultralow Magnetic Field Detection by Integrating Magnetoelastic Membrane on Film Bulk Acoustic Resonator

Machine learning-augmented surface-enhanced spectroscopy toward next-generation molecular diagnostics

“…73–85 The nanofabrication technologies for preparing SEIRA/SERS substrates include chemical preparation methods, photolithography, electron beam lithography, magnetron sputtering, electron beam evaporation, and more. 86–107 The widely used theory for modeling SERS/SEIRA includes perturbation theory, 108 temporal coupled-mode theory, 109,110 coupled harmonic oscillator theory, 111 and so on. As mentioned earlier, machine learning is complementary to SERS/SEIRA and offers unparalleled possibilities for solving pressing challenges related to spectral artifacts, overlapping, and huge volumes of spectral data (Fig.…”

Investigation of Elastic Softening and Stiffening Effect of Aluminum Nitride Under Stress Loading by Born‐Lande Equation

“…Currently, aluminum nitride piezoelectric thin film has been proven to be an excellent candidate for the realization of ultrahighfrequency acoustic devices attributed to its outstanding electrical and mechanical performance [1][2][3]. As a core functional material in acoustic resonators and filters, the elasticity of aluminum nitride piezoelectric thin film and its correlated intrinsic properties deserve priority attention.…”
