A self-assembled two-dimensional hypersonic phononic insulator.

ABSTRACT: The coupling between the electromagnetic field and the motional degrees of freedom of a nanoscale object offers an interesting control-knob for light-matter interaction. However, this interaction is rather weak so, in general, a precise control over the mechanical vibrations of the object becomes desirable for enhancing and fine-tuning this coupling. Phonon insulation is a base-line to achieve nanoscale vibration control by inducing constructive and destructive phonon interference, which opens phononic band gaps at various frequencies. Phonon insulators are essential for managing and directing mechanical vibrations in advanced mechanical systems, such as resonators and acousto-optic modulators. Conventional fabrication methods, such as electron-beam lithography, are highly robust and effic
