Research data for Random access actuation of nanowire grid metamaterial Pablo Cencillo-Abad, Jun-Yu Ou, Eric Plum, João Valente and Nikolay I Zheludev  The manuscript contains all information required to reproduce the results that it contains. Here, we make the full versions of the cropped scanning electron micrographs shown in the manuscript available. Fig2b.tif: Nanoscale gold contacts and gold areas for testing and metadevice fabrication made by e-beam lithography. Light grey areas show 50-nm-thick gold, darker areas show the silicon frame (covered with 50 nm of silicon nitride) and almost black areas show the 50-nm-thick freestanding silicon nitride membrane. Fig3a.tif: Scanning electron micrograph of the central membrane area with two contacted addressable reconfigurable nanomembrane metadevices and alignment marks for automated focused ion beam milling. A test pattern can be seen in the bottom right corner. Light grey areas show 50-nm-thick gold on 50-nm-thick silicon nitride, dark areas show the 50-nm-thick silicon nitride membrane, except in between the nanowires, where silicon nitride was also removed to separate the nanowires from each other. Fig3b.tif: High-resolution image of the nanowire grid metamaterial nanostructure. The nanowire grid metamaterial nanostructure is identical to those shown in Fig3a.tif, however, the image was taken on a different membrane chip prior to separating the nanowire contacts. A focused ion beam dose test can be seen at the top of the image. Light grey areas show 50-nm-thick gold on 50-nm-thick silicon nitride, dark areas show the 50-nm-thick silicon nitride membrane, except in between the nanowires, where silicon nitride was also removed to separate the nanowires from each other. Fig4b.tif: Scanning electron micrograph showing the nanostructure at a viewing angle of 50° from the normal with V3=3 V applied to nanowire 3 from the bottom. Light grey is gold, dark grey is silicon nitride, and black areas are fully cut through. Fig4c.tif: Scanning electron micrograph showing the nanostructure at a viewing angle of 50° from the normal without voltage application. Light grey is gold, dark grey is silicon nitride, and black areas are fully cut through. Fig4d.tif: Scanning electron micrograph showing the nanostructure at a viewing angle of 50° from the normal with V5=3 V applied to nanowire 5 from the bottom. Light grey is gold, dark grey is silicon nitride, and black areas are fully cut through.
