A Piezoelectric Stick-Slip Nanopositioning Stage With Ultra-High Load Capacity Realizing by Decoupling the Driving and Moving Units

open access: yesIEEE Access, 2019
The stick-slip piezoelectric stage plays an important role in micro-operation and industrial applications due to its nanometer resolution. However, under high load, the output performance of the piezoelectric stage will be seriously influenced.

Characterization and Design Framework for Micro‐ and Nanoscale Printed Metal Interconnects in Hybrid Electronic Systems

open access: yesAdvanced Materials Technologies, EarlyView.
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

open access: yesAdvanced Functional Materials, Volume 36, Issue 24, 23 March 2026.
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

open access: yesAnalysis &Sensing, Volume 6, Issue 2, March 2026.
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 ...

Narrow Linewidth Spontaneous and Lasing Emissions from Open‐Access Microcavity‐Embedded Perovskite Quantum Dots

open access: yesAdvanced Optical Materials, Volume 14, Issue 1, 9 January 2026.
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.

Butterworth pattern based simultaneous damping and tracking controller designs for nanopositioning systems

open access: yesFrontiers in Mechanical Engineering, 2016
The Butterworth filter is known to have maximally flat response. Incidentally, the same response is desired in precise positioning systems. This paper presents a method for obtaining a closed-loop Butterworth filter pattern using common control schemes ...

Nonlinear Control Design for a Piezoelectric-Driven Nanopositioning Stage [PDF]

open access: yes, 2005
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.
