In this paper, a graphene-based tunable filter with adjustable bandwidth and amplitude is proposed. The structure of filter consists of substrate integrated waveguide (SIW) and spoof surface plasmon ...

Hydration plays an important role in the diffusion and sieving of ions within nanochannels. However, it is hard to quantitatively analyze the contribution of hydration to the diffusion rates due to ...

The use of graphene electrodes plus a small cross-point structure are key elements to observe the tristate operation, which has not been observed in larger (100 μm × 100 μm) devices with an identical ...
