Atomic‐Scale Mechanisms of Anisotropic Thermal Decomposition in GeSn Alloys With Stepwise Pinning
Combining in situ TEM with DFT calculations, this work elucidates atomic‐scale anisotropic thermal decomposition in GeSn films, identifying laminar receding in defect‐free regions and stepwise pinning at stacking faults. Driven by crystallographic anisotropy and defect‐mediated energetic penalties, these findings establish a physical framework for ...

Coexistence of Large Nernst Effect and Axis‐Dependent Conduction Polarity in Semimetal MoSi2
MoSi2${\rm MoSi}_2$ is a rare material in which axis‐dependent conduction polarity (ADCP) and a large ordinary Nernst effect (ONE) coexist. The pronounced ONE (199μVK−1$199\,\umu \mathrm {V}\,\mathrm {K}^{-1}$) originates from nearly perfect carrier compensation, high mobility, and likely phonon drag, while ADCP arises from mixed‐dimensionality of the ...

Advancing Energy Materials by In Situ Atomic Scale Methods
Progress in in situ atomic scale methods leads to an improved understanding of new and advanced energy materials, where a local understanding of complex, inhomogeneous systems or interfaces down to the atomic scale and quantum level is required. Topics from photovoltaics, dissipation losses, phase transitions, and chemical energy conversion are ...

Thermoradiative Diodes Using Black Phosphorus van der Waals Materials
We demonstrate thermoradiative diodes based on black phosphorus (bP${\rm bP}$)/molybdenum disulfide (MoS2$MoS_2$) van der Waals heterojunctions which generate power by exchanging photons with a colder environment. The bandgap of black phosphorus is well positioned to exchange photons with outer space through the mid‐wave atmospheric window.
