Faraday effect in semiconductors [PDF]

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1962
Abstract This paper first reviews the general macroscopic and quantum mechanical formulae necessary for the calculation of Faraday rotations and Voigt shifts in semiconductors. The general formulae are then applied to calculate Faraday rotations, θ, in semiconductors as caused by: (i) allowed direct band-to-band transitions, (ii ...

A Multi‐Scale Machine Learning Framework for the Inverse Design of High Entropy Alloys

Advanced Engineering Materials, EarlyView.
High‐entropy alloys offer vast potential for various applications, including electrocatalysis; however, their compositional complexity challenges conventional screening. We introduce an inverse‐design framework combining two neural networks to determine optimal compositions and reconstruct nanoparticle geometry from targeted properties and conventional

Emulation of magneto-optic Faraday effect using ultracold atoms

New Journal of Physics, 2021
We propose an arresting scheme for emulating the famous Faraday effect in ultracold atomic gases. Inspired by the similarities between the light field and bosonic atoms, we represent the light propagation in medium by the atomic transport in accompany of

Faraday rotation estimation Performance analysis [PDF]

, 2010
Different Faraday Rotation (FR) estimators are discussed, their estimation performances are assessed and compared to each other. The algorithms are applied on a set of quad-pol ALOS Pal-SAR data and the obtained estimates are validated against FR values ...

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

Advanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

3-D Low Earth Orbit Vector Estimation of Faraday Rotation and Path Delay

IEEE Access, 2015
An electromagnetic wave propagating through the ionosphere is subject to path delay and the depolarizing effect of Faraday rotation, both of which are dependent on global position and geometry.

Zwitterionic Polymer Coating Enabled Chronic Dopamine Sensing and Electrophysiology Recording in Free‐Moving Mice

Advanced Healthcare Materials, EarlyView.
Application of a zwitterionic poly(sulfobetaine methacrylate) (PSB) coating to microelectrode arrays and Ag/AgCl reference electrodes effectively inhibits biofouling and structural degradation. This strategy successfully enables simultaneous, long‐term electrophysiological recording and dopamine sensing in freely behaving mice, facilitating ...

Limits to the Hall Effect and Other Nonreciprocal Effects in Three‐Dimensional Metamaterials

Advanced Materials, EarlyView.
Comprehensive and fundamental bounds on nonreciprocal effects in three‐dimensional metamaterials are derived. They reveal that the effective Hall mobility cannot exceed the largest constituent mobility, that, under certain conditions, the Verdet constant cannot be enhanced, and that, for constituents with Hall coefficients of the same sign, the largest

Optical properties and enhanced Faraday rotation in three-layer hybrid magneto-plasma crystals with C4h symmetry

Results in Physics
We investigate the optical properties and magneto-optical (MO) Faraday effect of a type of hybrid magneto-plasma crystal (HMPC) that is composed of a magnetic layer sandwiched between two Ag layers containing an array of holes.
