Single-crystal diamond nanomechanical resonators with quality factors exceeding one million.

Diamond has gained a reputation as a uniquely versatile material, yet one that is intricate to grow and process. Resonating nanostructures made of single-crystal diamond are expected to possess excellent mechanical properties, including high-quality factors and low dissipation. Here we demonstrate batch fabrication and mechanical measurements of single-crystal diamond cantilevers with thickness...

Functionalized Micromechanical Resonators with High Quality Factors

The dissipation of mechanical energy in 250-nm-thick, MHz-range silicon resonators is found to be strongly dependent on the chemical nature of the surface. As a result, sub-monolayer changes in the termination of 250-nm-thick resonators lead to significant changes in quality (Q) factor. The chemical origins of this effect are under investigation. Strategies for the formation of arbitrarily func...

Planar Resonators for Metamaterials

This paper presents the results of an investigation into a combination of electric and magnetic planar resonators in order to design the building element of a volumetric metamaterial showing simultaneously negative electric and magnetic polarizabilities under irradiation by an electromagnetic wave. Two combinations of particular planar resonators are taken into consideration. These planar reson...
