Dual-Optical-Comb Spectroscopic Ellipsometry [PDF]

open access: yesConference on Lasers and Electro-Optics, 2016
We proposed spectroscopic ellipsometry employing dual-optical-comb spectroscopy. We demonstrated the ellipsometric evaluation of a high-order quarter waveplate and a SiO 2 thin film standard with the spectral resolution of 48 MHz.

Surface Passivation of HgTe Nanocrystals Enabling EG/2 Open‐Circuit Voltage and Their Coupling to Dielectric Cavity for Narrow Detection

open access: yesAdvanced Materials, EarlyView.
This article explores how the integration of a thin shell, combined with optimized surface chemistry, enables the design of photodiodes based on short‐wave infrared HgTe nanocrystals. These photodiodes achieve an open‐circuit voltage greater than half the optical bandgap, which drastically reduces dark current. The article also explores the integration

Study on the Electrodeposition of Lead with In-Situ Ellipsometry

open access: yesInternational Journal of Electrochemical Science, 2015
In this study, we applied the in situ spectroscopic ellipsometry (SE) technology to the electrochemical test, and combined with cyclic voltammetry (CV) mainly researched underpotential-deposited (UPD) of Pb on polycrystalline Cu.

Rutile Without Substrate Limitations: Top‐Interface‐Driven Crystallization of TiO2

open access: yesAdvanced Materials, EarlyView.
A RuO2 upper layer acts as a removable crystallization template that triggers rutile TiO2 formation from the top interface, independent of the underlying substrate. This top‐interface‐driven crystallization mechanism enables rutile growth even on amorphous ZrO2/TiN, offering a substrate‐agnostic route to high‐k dielectrics compatible with DRAM process ...

Optical Properties of Bismuth Nanostructures Towards the Ultrathin Film Regime

open access: yes, 2019
Bulk bismuth presents outstanding optical properties, such as a giant infrared refractive index (n near 10) and a negative ultraviolet visible permittivity induced by giant interband electronic transitions. Although such properties are very appealing for

A Comparative Study on Early‐Stage Icing Evaluation Techniques for Passive Ice Protection Systems

open access: yesAdvanced Materials Interfaces, EarlyView.
This study addresses the lack of standardized methodologies for evaluating the early‐stage icing performance of passive ice protection systems. A unified experimental protocol is proposed and applied to representative hydrophilic and hydrophobic surfaces under controlled conditions.

Spectroscopic Ellipsometry Studies and Temperature Behaviour of the Dielectric Function of TlInS2 Layered Crystal [PDF]

open access: yesЖурнал нано- та електронної фізики, 2017
Real and imaginary parts of the dielectric function of TlInS2 single crystals in the spectral range from 1 to 5 eV were determined within a temperature range of 133–293 K from spectroscopic ellipsometry measurements.

Plasma‐Sequence‐Engineered Atomic Layer Deposition of Ultra‐Thin SiNx for Enhanced Etching Resistance in Extreme Ultraviolet Pellicles

open access: yesAdvanced Materials Interfaces, EarlyView.
Plasma‐sequence‐engineered ALD (PSE‐ALD), based on sequential NH3 and N2 plasma pulses, enables ultrathin, dense SiNx films. ToF‐MS analysis confirms ligand removal via HCl evolution, while increased film density indicates network densification. The resulting SiNx coating provides robust protection of graphite under H2 plasma exposure.
