Antenna In another development, silicon nanowire arrays were used [27]. Efficient procedures for fabrication of nanowires were recently developed [28,29]. Hemispherical gold deposits are made on the end of the wires. When a near-infrared optical field falls onto the gold deposits, it excites pla...
The use of periodic, nanostructured metallic arrays for sensing applications has been widely investigated [1]. By far, the most studied metals are gold and silver, which display useful optical phenomena that are sensitive to the local environment [2]. These phenomena are due to the coherent exci...
Consequently, the electrical and optical performances of nanoparticle-based films can be optimized by tailoring the length and functional groups of the nanoparticle ligands. This strategy has proven effective in enhancing the performance of nanoparticle-based films across diverse applications such as ...
Moreover, our sensor with such an unprecedented response capability can be operated as a barometric altimeter with an altitude resolution of about 1m. The outstanding behaviors of our devices make nanoparticle arrays for use as actuation materials for pressure measurement. 展开 ...
