Quick Optical Identification of the Defect Formation in Monolayer WSe2 for Growth Optimization

open access: yesNanoscale Research Letters, 2019
Bottom-up epitaxy has been widely applied for transition metal dichalcogenides (TMDCs) growth. However, this method usually leads to a high density of defects in the crystal, which limits its optoelectronic performance. Here, we show the effect of growth

Mechanism of Photocurrent Degradation and Contactless Healing in p-Type Mg-Doped Gallium Nitride Thin Films

open access: yesNanomaterials, 2022
Light-induced degradation (LID) phenomenon is commonly found in optoelectronics devices. Self-healing effect in halide lead perovskite solar cells was investigated since the electrons and holes in the shallow traps could escape easily at room temperature.

Optimizing Micro-Tiles in Micro-Structures as a Design Paradigm

open access: yesComputer-Aided Design, 2019
In recent years, new methods have been developed to synthesize complex porous and micro-structured geometry in a variety of ways. In this work, we take these approaches one step further and present these methods as an efficacious design paradigm. Specifically, complex micro-structure geometry can be synthesized while optimizing certain properties such ...

Enhancement of optical effects in zero-reflection metal slabs based on light-tunneling mechanism in metamaterials

open access: yesAIP Advances, 2012
Metals have many extraordinary optical properties. However, thick metals are nice mirrors, which prevent light penetrating deep into them. Since the skin depth is very thin, most optical properties of bulk metals are unavailable. In this paper, we review

Observation of modes reversion by encircling exceptional points in high-order non-hermitian system

open access: yesResults in Physics, 2023
The special properties of non-trivial topological structures usually come from a so-called edge mode which emerges in the band gap after the band inversion.

First-principles prediction of the electronic property, carrier mobility and optical absorption in edge-modified pristine sawtooth penta-graphene nanoribbons (SSPGNRs)

open access: yesResults in Physics, 2020
Based on the first-principle calculations, we systematically study the electronic property, carrier mobility and optical absorption spectra in the monohydrogen(H), dihydrogen(2H) and Al edge-modified pristine sawtooth penta-graphene nanoribbons (SSPGNRs),

A Simulation of Air Lasing Seeded by an External Wave in a Femtosecond Laser Filament

open access: yesSensors, 2023
Air lasers induced by femtosecond laser filaments play an important role in remote sensing applications. Few studies have been dedicated to the spatial distribution of external-seeded air laser radiation in the laser filament based on the numerical ...

Chromosome structure at micro-scale [PDF]

open access: yesNature Reviews Genetics, 2020
Two studies in Molecular Cell report fine-scale structural profiles of mammalian genomes using Micro-C, indicating that fine chromosomal structure is regulated by diverse transcription-related features.
