Efficient Polarization‐Entangled Photon‐Pair Generation by a Fiber‐In‐Line van der Waals Material

open access: yesAdvanced Science, EarlyView.
Telecom‐wavelength polarization‐entangled photon pairs are generated in a van der Waals‐material‐integrated all‐fiber device via spontaneous parametric down‐conversion. The demonstrated fiberized quantum light source bridges emerging 2D nonlinear materials and practical quantum photonic systems, opening new opportunities for scalable fiber‐based ...

Broadband Absorption Engineering to Enhance Light Absorption in Monolayer MoS2

open access: yes, 2016
Here we take a first step toward tackling the challenge of incomplete optical absorption in monolayers of transition metal dichalcogenides for conversion of photon energy, including solar, into other forms of energy.

Atomistic full-band simulations of monolayer MoS2 transistors [PDF]

open access: yes, 2013
We study the transport properties of deeply scaled monolayer MoS2 n-channel metal-oxide-semiconductor field effect transistors (MOSFETs), using full-band ballistic quantum transport simulations, with an atomistic tight-binding Hamiltonian obtained from ...

Ferroelectric Catalysts in the Hydrogen Evolution Reaction: A Perspective

open access: yesAdvanced Science, EarlyView.
This perspective summarizes recent advances in ferroelectric (FE) catalysts for the hydrogen evolution reaction (HER). It first introduces HER fundamentals and FE mechanisms, then classifies FE catalysts into single‐phase, single‐atom‐modified, heterostructured, and other engineered types, with representative examples.

Monolayer MoS2 and MoS2/Quantum Dot hybrids: novel optoelectronic materials

open access: yes, 2015
In this thesis we first briefly explore the barrier properties of monolayer graphene. We investigate how films of graphene can be used to decouple underlying metallic (Cu, Ni) substrate from the environment to passivate corrosion.

Engineering Dirac Cones in Graphene for Efficient Iodide Catalysis: Insights by Nanoscale Electrochemistry

open access: yesAdvanced Science, EarlyView.
Graphene iodide oxidation is regulated by Dirac cone engineering. Electrostatic gating tunes the Fermi level to control local iodide oxidation reaction activity, while magic‐angle twisted bilayer graphene creates flat‐band‐derived interfacial states that promote charge transfer and iodine‐species interaction, revealing a nanoscale route to electronic ...

Engineering in Oxygen-incorporated monolayer MoS2 for Effi-cient Hydrogen Evolution

open access: yesMedžiagotyra
MoS2 is a promising alternative to Pt in hydrogen evolution reaction (HER) due to its low cost. To enhance the catalytic properties of the 2H MoS2 inert basal plane, we propose an approach of employing oxygen incorporated MoS2 as a catalyst for HER ...

Influences of temperature gradient and distance on the morphologies of MoS2 domains

open access: yesAIP Advances, 2018
Monolayer molybdenum disulfide (m-MoS2) has attracted significant interest owing to its unique electronic and optical properties. Chemical vapor deposition has been well recognized as one of the preferred methods to prepare MoS2 film.

Intrinsic Phonons as a Dynamic Control Knob for Catalytic Reactivity in 2D Materials

open access: yesAdvanced Science, EarlyView.
Intrinsic phonon excitations are demonstrated to serve as a dynamic control knob for catalytic reactivity in 2D materials. Mode‐selective lattice vibrations reconstruct the electronic structure, lower oxygen evolution reaction barriers, establishing a phonon‐engineering paradigm for dynamically regulating electrocatalysis beyond conventional static ...
