Scaling of Hybrid QDs-Graphene Photodetectors to Subwavelength Dimension Open
Emerging colloidal quantum dot (cQD) photodetectors currently challenge established state-of-the-art infrared photodetectors in response speed, spectral tunability, simplicity of solution processable fabrication, and integration onto curve…

Focusing of Micrometer-Sized Metal Particles Enabled by Reduced Acoustic Streaming via Acoustic Forces in a Round Glass Capillary Open
Two-dimensional (2D) metal-particle focusing is an essential task for various fabrication processes. While acoustofluidic devices can manipulate particles in two-dimensions, the production of these devices often demands a cleanroom environ…

Metals by Micro‐Scale Additive Manufacturing: Comparison of Microstructure and Mechanical Properties Open
Many emerging applications in microscale engineering rely on the fabrication of 3D architectures in inorganic materials. Small‐scale additive manufacturing (AM) aspires to provide flexible and facile access to these geometries. Yet, the sy…

Defect-Tolerant Plasmonic Elliptical Resonators for Long-Range Energy Transfer Open
Energy transfer allows energy to be moved from one quantum emitter to another. If this process follows the Förster mechanism, efficient transfer requires the emitters to be extremely close (<10 nm). To increase the transfer range, nanophot…

Two-Dimensional Drexhage Experiment for Electric- and Magnetic-Dipole Sources on Plasmonic Interfaces Open
Fifty years ago, Drexhage et al. showed how photon emission from an electric dipole can be modified by a nearby mirror. Here, we study the two-dimensional analog for surface plasmon polaritons (SPPs). We print Eu^{3+}-doped nanoparticles, …

A customizable class of colloidal-quantum-dot metallic lasers and amplifiers Open
Colloidal quantum dots are robust, efficient, and tunable emitters now used in lighting, displays, and lasers. Consequently, when the spaser—a laser-like source of high-intensity, narrow-band surface plasmons—was first proposed, quantum do…

Colloidal-quantum-dot spasers and plasmonic amplifiers Open
Colloidal quantum dots are robust, efficient, and tunable emitters now used in lighting, displays, and lasers. Consequently, when the spaser, a laser-like source of surface plasmons, was first proposed, quantum dots were specified as the i…

Transparent Electrodes: Electrohydrodynamic NanoDrip Printing of High Aspect Ratio Metal Grid Transparent Electrodes (Adv. Funct. Mater. 6/2016) Open
D. Poulikakos and co-workers explain on page 833 how electro-hydrodynamic NanoDrip printing enables the fully additive fabrication of high-aspect-ratio nanostructures. Tiny gold nanoparticle ink droplets are ejected from a much larger nozz…
