On the Theory of Two-Photon Intersubband Absorption and Linear-Circular Dichroism in Semiconductors of the A3B5 Type

East European Journal of Physics
The frequency-temperature dependences of the probability of two-photon absorption (2PA), caused by transitions from the branch of light holes to the subband of spin-orbit splitting and linear-circular dichroism (LCD) associated with 2PA, as well as the ...

Wearable Smart Patches on Sustainable Chitosan With Reversible Microbial Growth‐Inhibitory Properties

Advanced Functional Materials, EarlyView.
ABSTRACT Chitosan, a polysaccharide upcycled from biowaste, has long promised sustainable, biocompatible, and antimicrobial films and devices, an appeal reinforced by its recent regulatory recognition, with several chitosan‐based antibacterial dressings gaining clearance through the Food and Drug Administration's 510(k) pathway.

COMPUTER SIMULATION OF METAL-SEMICONDUCTOR AND SEMICONDUCTOR-SEMICONDUCTOR INTERFACES

Le Journal de Physique Colloques, 1990
A Si-Ge interatomic potential was used to calculate the energy difference between strained and unstrained Ge layers on Si(001) substrates as a function of the number of layers . From this we estimate the critical thickness for dislocation nucleation to be less than 12 layers .

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Modeling of graphene wrapped indium antimonide nanowire as thermo-optical waveguide

Materials Research Express
In this research work, the fiber modes supported by the graphene-wrapped indium antimonide nanowire have been examined theoretically. The indium antimonide (InSb) is a semiconductor material, which has temperature-sensitive optoelectronic properties.

Chemical State Detection and Charge Transfer in Complex Oxide Heterostructures via In Situ Auger Electron Spectroscopy

Advanced Functional Materials, EarlyView.
In situ Auger Electron Spectroscopy resolves oxidation states with high fidelity during the pulsed laser deposition of multivalent perovskite manganate and vanadate heterostructures. The chemical‐state signature is carried by the valence‐electron population of the transition‐metal cation, read out through the relative intensities of Auger fine ...
