Vortex Domain Wall Imaging in a 3D Magnetic Nanotube Grown by Focused Electron Beam Induced Deposition

open access: yesSmall, EarlyView.
Synthesis of nanoscale high‐purity Co magnetic nanotubes using a single growth technique, focused electron beam induced deposition (FEBID). Utilizing electron holography and micromagnetic simulations, we demonstrate the nucleation and pinning of tilted vortex domain walls, providing crucial experimental evidence to advance 3D spintronics and ...

High-efficiency, broadband, and low-crosstalk 3D holography by multi-layer holographic-lens integrated metasurface

open access: yesAPL Photonics
Holographic display is considered the holy grail of photorealistic three-dimensional (3D) visualization technology because it can provide arbitrary wavefronts related to the essential visual cues of 3D images.

Precise Nanoscale Mapping of Electric Fields Across Random Grain Boundaries in Polycrystalline Oxides Using Precession‐Assisted 4D‐STEM

open access: yesSmall, EarlyView.
Correlative singular value decomposition 4D‐STEM analysis of the potential, electric field, and charge density distributions with crystal orientation, strain across grain boundaries in polycrystalline materials. ABSTRACT Space charge layers (SCLs) at grain boundaries play a crucial role in modulating electric fields and thereby influence functional ...

Identification and Size Estimation of Non-Spherical Nanoparticles using Polarization-Resolved Holography

open access: yes, 2020
Dual-view polarization-resolved digital holography is used to record the polarization response of the scattered light from both spherical and non-spherical nanoparticles. A model based on the T-matrix method is developed to map the polarization to a size

Meter-depth and multi-polarization addressable zoom 3D meta-holography

open access: yesNature Communications
Propelled by rapid advances in nanofabrication, meta-holography has become a frontier hot spot in optics. 3D meta-holography, in particular the large depth and multi-polarization addressable ones, with extraordinary expansion of the control dimension and

Development of a Holographic Directional Volumetric Display

open access: yesIEEE Access
In previous studies, we introduced a directional volumetric display which can project in multiple directions by superimposing different two-dimensional images in three-dimensional space.

Energy‐Resolved Localized Surface Plasmon Resonances With Non‐Monochromated STEM‐EELS Assisted by Multivariate Analysis

open access: yesSmall Methods, EarlyView.
Transmission Electron Microscopy is a powerful technique, able to provide morphological, chemical, and optical/electronic information, yet some of these features require the use of highly expensive machines such as monochromated microscopes. In this work, we used low dose, low voltage, and mathematical treatment to gain energy resolution in an ...

Photochromic materials for holography: issues and constraints

open access: yes, 2012
Photochromic materials can find application in holography, thanks to the peculiar possibility to change reversibly their transparency in the visible (amplitude holography) and their refractive index in the near infrared region (phase holography).

Recent advances in atomic resolution three-dimensional holography

open access: yesAdvances in Physics: X
Three-dimensional (3D) local atomic structure around specific functional atom plays a crucial role in functional materials, but it has not been able to be analyzed by a standard structure analysis method of x-ray diffraction (XRD) because this kind of ...

Hyperspectral and Multispectral Image Fusion via Deep Generalised Linear Mixed Model

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Hyperspectral–multispectral image fusion is an incomplete information fusion problem, and directly embedding information can lead to modality‐specific responses and cause spectral distortion, whereas the strong interband redundancy of hyperspectral images makes full‐dimensional fusion inefficient.
