The effect of elastic anisotropy on contrast in the scanning acoustic microscope

Philosophical Magazine A, 1984
Abstract The contrast obtained with polycrystalline specimens in the scanning acoustic microscope is computed by taking account of the anisotropic stiffness tensor. The resulting variation of signal with defocus is fundamentally different from that which could be obtained with an isotropic material regardless of the values of the elastic properties. In

Tailoring Phonon‐Driven Responses in α‐MoO3 through Isotopic Enrichment

Advanced Materials, EarlyView.
ABSTRACT The implementation of polaritonic materials into nanoscale devices requires selective tuning of parameters to realize desired spectral or thermal responses. One robust material, α‐MoO3, an orthorhombic crystal boasting three distinct phonon dispersions, provides three polaritonic dispersions of hyperbolic phonon polaritons (HPhPs) across the ...
