Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Phase retrieval algorithm for line-scan dispersive interferometry

Other Conferences, 2018
The line-scan dispersive interferometry (LSDI) benefits from single-shot measurement in nature and has potential to perform in-line surface metrology. In this technique, the interference beam produced by the two arms of the interferometer is spatially ...

Imaging of Biphoton States: Fundamentals and Applications

Advanced Functional Materials, EarlyView.
Quantum states of two photons exhibit a rich polarization and spatial structure, which provides a fundamental resource of strongly correlated and entangled states. This review analyzes the physics of these intriguing properties and explores the various techniques and technologies available to measure them, including the state of the art of their ...

A noise-immune cavity-assisted non-destructive detection for an optical lattice clock in the quantum regime [PDF]

, 2017
We present and implement a non-destructive detection scheme for the transition probability readout of an optical lattice clock. The scheme relies on a differential heterodyne measurement of the dispersive properties of lattice-trapped atoms enhanced by a

Absolute distance measurement with correction of air refractive index by using two-color dispersive interferometry.

Optics Express, 2016
Two-color interferometry is powerful for the correction of the air refractive index especially in the turbulent air over long distance, since the empirical equations could introduce considerable measurement uncertainty if the environmental parameters ...

Enhancing Stability of Few‐Layer Black Phosphorus (FLBP) Through Nitrocellulose Coating: A Robust Defense Mechanism Against Degradation

Advanced Materials Interfaces, EarlyView.
In this research, a simple and scalable strategy for protection of a few‐layer black phosphorus (FLBP) with a cellulose nitrate‐based material is presented. The FLBP is structurally and morphologically characterized. The FLBP stability with and without nitrocellulose protection is monitored by interferometric method, surface profile examination, and ...
