Moiré photonics and optoelectronics | Science - AAAS
Feb 24, 2023 · Moiré pattern refers to a new, long-length scale of structure arising from the interference between two or more periodic templates. The scientific and engineering value of moiré patterns was firstly appreciated by the physicist Lord Rayleigh in 1874.
Moiré patterns in nanomaterials - ScienceDirect
Mar 15, 2022 · The moiré patterns are studied by Transmission Electron Microscope (TEM), High Resolution Transmission Electron Microscope (HRTEM), Scanning Tunnelling Microscope (STM) and Low Energy Electron Diffraction (LEED).
The Hide-and-Seek of Grain Boundaries from Moiré Pattern
Jul 28, 2015 · A general moiré pattern consists of a rotational moiré pattern and a translational moiré pattern, which is induced by the lattice mismatch between layers.
Combining moiré patterns and high resolution transmission …
Jan 1, 2011 · This paper reports the coupling of HRTEM and moiré pattern observations, allowing the determination of the thickness ratio of two superimposed crystals. Pseudo-lattice fringes are observed using identical TEM experimental conditions as for observing moiré patterns.
The Scanning Secondary Moiré Method with Atomic-Level
Jan 2, 2025 · The scanning secondary moiré patterns were generated when the scanning spacing was close to the TEM moiré spacing. Through this method, the deformation field, mechanical properties, and internal defects of crystals can be detected by a large field of view with high sensitivity and high efficiency.
Moire Fringes in Transmission Electron Microscopy - J-STAGE
Feb 26, 2018 · Moire fringes are observed when two (or more) crystal lattices are interfered in transmission electron microscopy (TEM). Typical application is the evaluation of epitaxial films grown on a substrate, in where their crystallographic orientation relationship could be investigated.
