Reduction of power consumption is the key target for modern electronic devices. To this end, a lot of attention is paid to zero-static power switches, being able to change their state between highly resistive and highly conductive and remain in this state even in the absence of external voltage. Still, the implementation of such switches is slow because of compatibility issues of new materials with CMOS technology. At the same time, printable technology enables low-cost processes at ambient temperature and integration of devices onto flexible substrates. Here we demonstrate that printed Ag/MoS/Ag heterostructures can be used as zero-static power switches in radiofrequency/microwave spectrum and fully-integrated reconfigurable metasurfaces. Combined with graphene, our printed platform enables reconfigurable metasurface for electromagnetic wave manipulation and control for wireless communications, sensing, and holography. In addition, it is also demonstrated that the localised MoS phase change may have promoted Ag diffusion in forming conductive filaments.
降低功耗是现代电子设备的关键目标。为此,零静态功耗开关备受关注,这种开关能够在高电阻和高导电状态之间切换,并且即使在没有外部电压的情况下也能保持在该状态。然而,由于新材料与CMOS技术的兼容性问题,此类开关的实现速度较慢。同时,印刷技术能够在环境温度下实现低成本工艺,并将器件集成到柔性基板上。在此,我们证明印刷的Ag/MoS/Ag异质结构可作为射频/微波频段的零静态功耗开关以及完全集成的可重构超表面。与石墨烯相结合,我们的印刷平台能够实现用于电磁波操纵和控制的可重构超表面,以用于无线通信、传感和全息术。此外,还证明了局部的MoS相变可能促进了Ag在形成导电细丝过程中的扩散。
