Nanoscale Conical Swiss Roll with Broadband Visible and NIR Circular Dichroism

A new strategy based on dynamic shadowing growth is developed to fabricate Swiss roll chiral metamaterials in nano­scale. The fabricated Swiss roll nano­structures exhibit broadband circular dichroism response in visible to near‐IR wavelength region. Importantly, this strategy allows the dimension o...

Zusammenfassung:A new strategy based on dynamic shadowing growth is developed to fabricate Swiss roll chiral metamaterials in nano­scale. The fabricated Swiss roll nano­structures exhibit broadband circular dichroism response in visible to near‐IR wavelength region. Importantly, this strategy allows the dimension of Swiss rolls to be easily tuned, which subsequently changes their chiral optical properties.
