摘要

近年来，非易失性电阻开关记忆效应在二维(2D)过渡金属二硫族化合物和氮化硼中得到了积极的研究，以推进未来记忆和神经形态计算的应用。在这里，我们报告了使用六方氮化硼(h-BN)忆阻器的射频(RF)开关，该开关可在毫米波(mmWave)范围内工作。值得注意的是，h-BN的银(Ag)电极具有出色的非易失性双极电阻开关特性，具有1011的高开/关开关比和低于0.34 V的低开关电压。此外，该开关在d频段频谱(110至170 GHz)上具有0.50 dB的低插入损耗和23 dB的高隔离。此外，S21的插入损耗可以通过5个数量级的电流顺应性来调节，这增加了原子开关的应用前景。这些结果可以使交换机成为未来可重构无线和6G通信系统的关键组件。

Reconfigurable Low-Voltage Hexagonal Boron Nitride Nonvolatile Switches for Millimeter-Wave Wireless Communications

Recently, nonvolatile resistive switching memory effects have been actively studied in two-dimensional (2D) transition metal dichalcogenides and boron nitrides to advance future memory and neuromorphic computing applications. Here, we report on radiofrequency (RF) switches utilizing hexagonal boron nitride (h-BN) memristors that afford operation in the millimeter-wave (mmWave) range. Notably, silver (Ag) electrodes to h-BN offer outstanding nonvolatile bipolar resistive switching characteristics with a high ON/OFF switching ratio of 10¹¹ and low switching voltage below 0.34 V. In addition, the switch exhibits a low insertion loss of 0.50 dB and high isolation of 23 dB across the D-band spectrum (110 to 170 GHz). Furthermore, the S₂₁ insertion loss can be tuned through five orders of current compliance magnitude, which increases the application prospects for atomic switches. These results can enable the switch to become a key component for future reconfigurable wireless and 6G communication systems.
