Mechanical dissipation by substrate-mode coupling in sin resonators

HIGHLIGHTS

  • who: Matthijs H. J. de et al. from the Department Delft University The Netherlands have published the article: Mechanical dissipation by substrate-mode coupling in SiN resonators, in the Journal: (JOURNAL)
  • what: The authors build on this latter direction by linking it to the well-known effect of dissipation in resonant coupled resonators23 and show that coupling between resonator and substrate modes can negatively affect the Q-factor of trampoline resonators15 despite their difference in size. The authors show that the substrate can even mediate resonant coupling between two resonators separated by 1.5 mm . . .
