A New Optical Configuration for the Surface Encoder with an Expanded Z-Directional Measuring Range

Sensors, 2022
This paper proposes a new optical configuration for a two-axis surface encoder that can measure the in-plane (X-axis) and out-of-plane (Z-axis) displacements of a positioning stage. The two-axis surface encoder is composed of a scale grating and a sensor

Direct and alignment-insensitive measurement of cantilever curvature [PDF]

, 2013
We analytically derive and experimentally demonstrate a method for the simultaneous measurement of deflection for large arrays of cantilevers. The Fresnel diffraction patterns of a cantilever independently reveals tilt, curvature, cubic and higher order ...

Uncertainty Evaluation for Measurements of Pitch Deviation and Out-of-Flatness of Planar Scale Gratings by a Fizeau Interferometer in Littrow Configuration

Applied Sciences, 2018
Form errors of a planar scale grating, such as pitch deviations and out-of-flatness, are major contributors to the final measurement uncertainty of an interferential scanning-type planar encoder.

The European nanometrology landscape

Nanotechnology, 2011
This review paper summarizes the European nanometrology landscape from a technical perspective. Dimensional and chemical nanometrology are discussed first as they underpin many of the developments in other areas of nanometrology. Applications for the measurement of thin film parameters are followed by two of the most widely relevant families of ...

Ethical Challenges in Nanometrology [PDF]

Communications - Scientific letters of the University of Zilina, 2018
Nanometrology is an intrinsic and fast developing part of nanoscience. Given the huge diversity of nanostructures ranging from large molecules from about 10 atoms to structures from 105 atoms (particles of the size ≤ 100 nm), broader investigations in this area cannot be exactly scrutinized nor repeated by the existing capacities. This gave rise to the

Toward three-dimensional hybrid inorganic/organic optoelectronics based on GaN/oCVD-PEDOT structures

Nature Communications, 2020
Though integrating functional organic materials with semiconductor nanostructures is attractive for 3D chip processing, realizing these hybrids remains a challenge.

Ultraviolet Raman Spectroscopy of Single and Multi-layer Graphene

, 2009
We investigated Raman spectra of single-layer and multi-layer graphene under ultraviolet laser excitation at the wavelength of 325 nm. It was found that while the G peak of graphene remains pronounced in UV Raman spectra, the 2D band intensity undergoes ...

Investigation and Improvement of Thermal Stability of a Chromatic Confocal Probe with a Mode-Locked Femtosecond Laser Source

Applied Sciences, 2019
An intentional investigation on the thermal stability of a mode-locked femtosecond laser chromatic confocal probe, which is a critical issue for the probe to be applied for long-term displacement measurement or surface profile measurement requiring long ...

Crystal Symmetry Breaking in Few-Quintuple Bismuth Telluride Films: Applications in Nanometrology of Topological Insulators

, 2010
We report results of micro-Raman spectroscopy investigation of the "graphene-like" mechanically exfoliated single-crystal bismuth telluride films with the thickness ranging from a few-nm-range to bulk limit.

Observation of anomalous decoherence effect in a quantum bath at room temperature [PDF]

, 2011
Decoherence of quantum objects is critical to modern quantum sciences and technologies. It is generally believed that stronger noises cause faster decoherence. Strikingly, recent theoretical research discovers the opposite case for spins in quantum baths.
