Signal transformation approach to fast nanopositioning

open access: yesReview of Scientific Instruments, 2009
High bandwidth, high resolution positioning is a significant enabling tool for nanotechnology. Unfortunately, in a typical nanopositioner operating in closed loop, higher bandwidth results in increased sensitivity to measurement noise and hence reduced resolution. In this article we present a technique that allows high-precision tracking of repetitive,

All-Optical Nanopositioning of High-Q Silica Microspheres [PDF]

open access: yes, 2017
A tunable, all-optical, coupling method has been realized for a high-\textit{Q} silica microsphere and an optical waveguide. By means of a novel optical nanopositioning method, induced thermal expansion of an asymmetric microsphere stem for laser powers ...

Development and testing of a XYZ scanner for atomic force microscope [PDF]

open access: yes, 2017
Atomic force microscopy (AFM) is a widely used tool in nano measurement and manipulation techniques. However, a traditional AFM system suffers from the limitation of slow scanning rate, due to the low dynamic performance of piezoelectric positioners.

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.

Optical Skyrmions Modulation Based on Polarization Helicity

open access: yesNanophotonics, Volume 15, Issue 9, 13 May 2026.
The polarization helicity represents the global twisted property of the polarization state distribution, it can be used to modulate the spin skyrmion texture in the tight focusing of the radially polarized vortex light. By adjusting the polarization helicity of incident field, the Néel‐Bloch‐Néel transition of the spin skyrmion texture can be realized,

Fast Parameter Identification of the Fractional-Order Creep Model

open access: yesActuators
In this study, a parameter identification approach for the fractional-order piezoelectric creep model is proposed. Indeed, creep is a wide-impacting phenomenon leading to time-dependent deformation in spite of constant persistent input.

Experimental Validation of Ultra-Precision Nanopositioning System

open access: yesIEEE Access, 2021
In this paper, the development of an ultra-precision XY nanopositioning stage is presented. For system structure, the actuator decoupled parallel compliant mechanism is designed to have the same dynamics in both x- and y-direction so that the coupling ...

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.
