TL;DR: This work reveals the feasibility to realize tunable/active and extremely low-profile polarization manipulation devices in the terahertz regime through the incorporation of such phase-change metasurfaces, enabling novel applications of ultrathin terAhertz meta- devices.

TL;DR: In this paper, a phase-change metasurface was used for multiband tunable active terahertz polarization control, which achieved linear-to-circular polarization at 0.45 and 1.10 GHz with an ellipticity of 0.998 and $-$ 0.971, respectively.

TL;DR: The present results suggest that high-mobility oxide interfaces, which exhibit quantum phenomena, could be obtained by ionic liquid-assisted field effect.

TL;DR: In this article, an ionic liquid-assisted electric field effect was used to tune the carrier density in an electron-doped cuprate ultrathin film and cause a two-dimensional superconductor insulator transition (SIT).

TL;DR: In this paper, the authors explore deep x-ray lithography and subsequent stacking of chips to fabricate, with good yield, substantial quantities of rod-split-ring structures that come closer to three dimensions than before.
