“…This set of experiments seemingly shows that the pore membrane can support water on one side without wetting the other side, probably owing to the relatively hydrophobic surface property of AlN. 47 In order to gain a better understanding of the immersion processes, we simulated the extinction spectra for the corresponding LRO structures in different immersion configurations: (i) entirely in air, (ii) only top side in water with the pore unfilled, (iii) top side and inside of the pore in water, and (iv) entirely in water. The simulated spectra are shown in Figure 3e, and the resonance shift with respect to the simulated position in air is plotted as rhombuses in Figure 3d, superimposed on the experimental curve.…”

Suspended plasmonic nanopores in ultrathin film layers were fabricated through a simple and widely applicable method combining colloidal lithography and thin film transfer, which allows mass production of short-range ordered nanopore arrays on a large scale. By this combined method, mechanically stable and flexible free-standing nanopore membranes with a thickness down to 15-30 nm were produced. The plasmon resonances of the ultrathin plasmonic nanopores fabricated in AlN/Au/AlN trilayer and single layer Au membranes were tuned to lie in the vis-NIR wavelength range by properly designing their dimensions. The optical responses to the refractive index changes were tested and applied to adlayer sensing. The trilayer nanopore membrane showed a unique property to support water only on one side of the membrane, which was confirmed by the resonance shift and comparison with numerical simulation. Pore size reduction down to 10 nm can be achieved through additional material deposition. The filtering function of such pore-size-reduced conical shaped nanofunnels has also been demonstrated. The presented nanopore fabrication method offers new platforms for ultrathin nanopore sensing or filtering devices with controlled pore-size and optical properties. The film transfer technique employed in this work would enable the transformation of any substrate-based nanostructures to free-standing membrane based devices without complicated multiple etching processes.

“…This is associated with the laser induced texturing of the surface and the presence of AlN compound at the surface, which is formed during the laser treatment process. In this case, the surface free energy of AlN is 38.3 mJ/m 2 [46] when compared to 93.9 mJ/m 2 for Al [47]. The low surface energy of AlN (γ sl ) enhances the contact angle for the laser treated surface.…”

Graphene oxide (GO) is a promising candidate for humidity sensing, and the uniformity and thickness of GO films are important for the reproducibility and test signal strength of humidity sensors. In this paper, uniform and thickness-controllable GO films are first formed by the surface tension of different concentrations of GO solution and then transferred to surface acoustic wave (SAW) humidity sensors. This GO film formation and transfer process has very good repeatability and stability, as evidenced by the humidity response of the sensors. With the help of the uniform and highly oxidized GO film, the humidity sensors show a significantly high sensitivity (absolute sensitivity of 25.3 kHz/%RH and relative sensitivity of 111.7 p.p.m./%RH) in a wide test range from 10%RH to 90%RH with very little hysteresis (<1%RH). The sensors achieve good reversibility, excellent short-term repeatability and stability. Moreover, the humidity sensors also show a fast response and recovery time of <10 s.
