Dissipation mechanisms in thermomechanically driven silicon nitride nanostrings
Dissipation mechanisms in thermomechanically driven silicon nitride nanostrings
High-stress silicon nitride nanostrings are a promising system for sensing applications because of their ultra-high mechanical quality factors (Qs). By performing thermomechanical calibration across multiple vibrational modes, we are able to assess the roles of the various dissipation mechanisms in these devices. Specifically, we possess a set of nanostrings in …
