Electrically Driven Varifocal Silicon Metalens
Electrically Driven Varifocal Silicon Metalens is a scholarly work, published in 2018 in ''ACS Photonics''. The main subjects of the publication include optics, metamaterial, silicon, optoelectronics, nanotechnology, memristor, graphene, and materials science. The authors\ndemonstrate precise and continuous tuneability of the focal length and achieve\nfocal length variation larger than the Rayleigh length for voltage as small as\n12 volts.
