Metal/metal oxides have attracted extensive research interest because of their combination of functional properties and compatibility with industry. Diffusion and thermal reliability have become essential issues that require detailed study to develop atomic‐scaled functional devices. In this work, the diffusional reaction behavior that transforms piezoelectric ZnO into magnetic Fe3O4 is investigated...
Plasmonic nanopores combine the advantages of nanopore sensing and surface plasmon resonances by introducing confined electromagnetic fields to a solid‐state nanopore. Ultrasmall nanogaps between metallic nanoantennas can generate the extremely enhanced localized electromagnetic fields necessary for single‐molecule optical sensing and manipulation. Challenges in fabrication, however, hamper the integration...
When designing a new nanostructure or microstructure, one can follow a processing‐based manufacturing pathway, in which the structure properties are defined based on the processing capabilities of the fabrication method at hand. Alternatively, a performance‐based pathway can be followed, where the envisioned performance is first defined, and then suitable fabrication methods are sought. To support...
In article number 1801503, Jennifer A. Hollingsworth and co‐workers demonstrate an advance in nanofabrication using dip‐pen nanolithography (DPN) to directly place nanocrystal quantum dots onto a three‐dimensional nanostructured optical antenna. The results lay the groundwork for the expanded use of DPN and other scanning probe technologies for the additive preparation of functional multi‐component...
Dip‐pen nanolithography (DPN) is used to precisely position core/thick‐shell (“giant”) quantum dots (gQDs; ≥10 nm in diameter) exclusively on top of silicon nanodisk antennas (≈500 nm diameter pillars with a height of ≈200 nm), resulting in periodic arrays of hybrid nanostructures and demonstrating a facile integration strategy toward next‐generation quantum light sources. A three‐step reading‐inking‐writing...
In article number 1803471, Johnas Eklöf‐Österberg, Kasper Moth‐Poulsen, and co‐workers make isolation, positioning, and electronic measurements on single molecules possible using a combined top‐down and bottom‐up strategy. Proto‐devices, which are self‐assembled nanogaps composed of two gold nanoparticles linked by a single or a few molecules, are guided onto top‐down prefabricated nanosized electrodes...
Single molecule electronics might be a way to add additional function to nanoscale devices and continue miniaturization beyond current state of the art. Here, a combined top‐down and bottom‐up strategy is employed to assemble single molecules onto prefabricated electrodes. Protodevices, which are self‐assembled nanogaps composed by two gold nanoparticles linked by a single or a few molecules, are...
