摘要

We introduce a class of nanoresonators that incorporate a new degree of freedom: twist tuning. To achieve this result, we place a pristine slab of the van der Waals α-MoO3 crystal on an array of metallic ribbons. This sample design based on electromagnetic engineering, allows the definition of-MoO3 nanoresonators with low losses (Q up to 200) and enables a broad spectral tuning of the polaritonic resonances (up to 32 cm-1) by an in-plane rotation (from 0 to 45º).
