Achieving Uniform Phase Structure for Layer-by-Layer Processed Binary Organic Solar Cells with 20.2% Efficiency
Layer-by-layer (LBL) deposition has become a facile and promising method to fabricate highly efficient organic solar cells (OSCs). However, characterization and optimization of 3D morphology remain a grand challenge for LBL- processed active layers, and their correlation with photovoltaic properties of OSC devices is not clear to date.
Here, to address this issue, ...
Spin density wave and van Hove singularity in the kagome metal CeTi3Bi4
Kagome metals with van Hove singularities near the Fermi level can host intriguing quantum phenomena such as chiral loop currents, electronic nematicity, and unconventional superconductivity. However, to our best knowledge, unconventional magnetic states driven by van Hove singularities–like spin-density waves–have not been observed experimentally in kagome metals. Here, we report ...
4D imaging of frost heave and ice lens growth in silt using neutron and x-ray computed tomography
There are substantial changes in soil structure in regions where the soil is freezing. Water movements in the freezing soil introduce level changes beyond what can be expected by the expansion of water when it freezes. The impact of frost heave is seasonal damage to our built environment ...
