Time‐Modulated Optomechanics Reveal Energy Flow and Inelastic Interactions Between Acoustic Phonons in Nanomembranes

Anuj Kumar Dhiman, Piotr Graczyk, Tobias Held, Mikolaj Pochylski, Kleoniki Sympoura, Rafal Bialek, Jacek Gapinski, Bahram Djafari-Rouhani, Baerbel Rethfeld, Bartlomiej Graczykowski, Thomas Vasileiadis

<div><p>An abrupt change in refractive index, known as a temporal interface, can cause temporal reflection, refraction, and diffraction of light, enabling the development of time-varying photonic devices. Since time-varying optics are based on ultrafast electronic excitations, the…

Competing regimes of charge-carrier and impurity scattering limiting phonon heat conduction in heavily-doped silicon

Raja Sen, Juan Carlos Acosta Abanto, Mélanie Brouillard, Séverine Gomès, Jean-François Robillard, Alessandro Ciavatta, Lorenzo Paulatto, Nathalie Vast, Jérôme Saint-Martin, Jelena Sjakste, Pierre-Olivier Chapuis

With respect to undoped semiconductors, thermal transport by phonons is limited by two additional mechanisms when doping increases: charge-carrier and impurity scattering. Previous works provided contradicting conclusions on the dominant doping-induced scattering mechanism in silicon. In this work…
