Nanowire composite and preparation method thereof

A resonator comprising:

• a nanowire composite including:
• a template having a first surface, a second surface opposite to and parallel to the first surface, and a third surface extending from the first surface to the second surface:
• a plurality of hollow channels disposed in the template and extending therein from the first surface and the second surface;
• nanowires disposed in the plurality of hollow channels;
• and
• a functional element comprising a portion of one or more of the nanowires exposed through an etched portion of the third surface of the template,
• wherein the functional element does not directly touch the first surface or the second surface of the template.
