This work establishes a framework for high‐resolution printed interconnects by coupling e‐jet printing control, multilayer deposition, and sintering optimization. Ink properties and printing speed influence particle stacking, while different sintering atmospheres drive distinct microstructural evolution.

Deterministic hBN Bubbles as a Versatile Platform for Studies on Single‐Photon Emitters
Single‐photon emitters (SPEs) in hBN are promising for quantum technologies; however, in exfoliated samples their activation is required, limiting reproducibility of previous studies. This work introduces a large‐area MOVPE‐grown hBN platform that hosts SPEs without prior activation.

Plasmonic Bi‐Cavity Nanostructure for Efficient Light Collection and Localization
Co‐tuning the plateau and pyramid lengths of a pyramid‐on‐plateau nanostructure creates a hybrid antenna‐cavity that efficiently couples low‐NA excitation and funnels energy to the apex, increasing nano‐Raman signal and enabling TERS in geometries previously inaccessible to high‐NA objectives.Tip‐enhanced Raman spectroscopy (TERS) typically relies on ...

Continuous‐wave lasing from a small number of perovskite quantum dots is achieved by coupling their photoluminescence to open‐access curved dielectric cavities. This geometry confines their emission into a single optical mode, sharply narrowing linewidths in both spontaneous and lasing regimes.

Nonlinear Control Design for a Piezoelectric-Driven Nanopositioning Stage [PDF]
Abstract : A model-based nonlinear optimal control design is developed and applied to a piezoelectric-driven nanopositioning stage to demonstrate high accuracy displacement control when ferroelectric nonlinearities, hysteresis and relaxation behavior are present in the piezoelectric actuator.
