Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Switchable Magnonic Crystals Based on Spin Crossover/CrSBr Heterostructures

open access: yesAdvanced Materials, EarlyView.
Multiscale modeling is employed to investigate the functionality of a light‐controlled, tunable magnonic crystal based on spin‐crossover Fe‐pz molecules integrated with a monolayer of CrSBr. Ab initio simulations confirm that the molecules remain functional on the CrSBr surface, while a semiclassical elastic model demonstrates that light‐induced ...

Application of improved cutterhead technology of shield machine in anchor cable zones

open access: yesFrontiers in Earth Science
The shield crossing an anchor cable zone can cause the anchor cable to wrap around the cutter, creating construction problems. To address this issue, we developed an improved cutterhead technology for the shield machine which was successfully used during

Large‐Scale Determination of Frontier Orbital Energies of Disordered Small‐Molecule Organic Semiconductors Using Exciplex Emission Spectra

open access: yesAdvanced Materials, EarlyView.
ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

MOCVD‐Grown MoS2 Wafers as a Transfer‐Free Platform for Top‐Gate Devices via Dry Interface Engineering

open access: yesAdvanced Materials, EarlyView.
We reveal the electronic origin of hidden interfacial doping in monolayer MoS2 grown by MOCVD, identifying sulfate related and water like species as intrinsic donors. Through dry interface engineering approach, we demonstrate MOCVD‐grown single‐crystal MoS2 wafers as a transfer‐free platform for the reliable evaluation of intrinsic gate stacks and ...

Application of Modified Peck Formula for Metro Shield Tunneling Construction inWater-bearing Sandy Soil Layers in Nanchang

open access: yesChengshi guidao jiaotong yanjiu
[Objective] Due to the influence of geological conditions, tunnel burial depth, tunnel diameter, and properties of the overlying soil layer, the Peck formula exhibits significant deviations when applied to the shield tunneling construction in water ...

Photo‐ and Thermally‐Induced Huge Layer Decoupling in Twisted Bilayer WSe2

open access: yesAdvanced Materials, EarlyView.
A newly developed automated dark‐field tomography visualizes twist‐angle‐dependent structural relaxation and quantifies 3D structures in twisted bilayer WSe2. This approach reveals the evolution of local stacking configurations, thermally induced sub‐ångström interlayer decoupling, and light‐driven interlayer expansion on picosecond timescales ...

Comparative Analysis of Work Function Measurement Techniques Based on Scanning Probe Microscopy

open access: yesAdvanced Materials, EarlyView.
Non‐contact scanning probe microscopy visualizes the surface topography based on surface electronic properties. The tunneling current, which defines the geometry of the tunnel–junction, has to overcome the effective surface work function barrier to reach the probe from the surface.
