Understanding thermal transport at the nanoscale is crucial for the design of efficient heat dissipation pathways in modern devices, including densely integrated electronics, plasmonics and quantum material-based systems [1]. As device dimensions continue to decrease, nanoscale thermal transport becomes increasingly important to …

As silicon hits its physical limits, epitaxial graphene on SiC has emerged as a high-performance successor. While standard graphene lacks a bandgap, the semiconducting "buffer layer" (BL) on the SiC(0001) facet provides a ∼0.6 eV gap and hole mobilities superior to germanium, …

Momentum-resolved vibrational electron energy-loss spectroscopy (EELS) in scanning transmission electron microscopy (STEM) enables the mapping of phonon dispersions from nanometer-sized regions, greatly surpassing the spatial resolution of inelastic neutron scattering (INS) and inelastic X-ray scattering (IXS).While first implementations of momentum-resolved vibrational EELS …

Understanding heat transport at the nanometer scale is critical for semiconductor devices, quantum materials, and thermal management of nanostructures, yet direct local measurements of thermal conductivity and heat capacity remain scarce. We developed a laser-excitation system integrated into a scanning transmission electron …

In surface soils and sediments, iron monosulfide (FeS) species, including nanocrystalline mackinawite, tend to quickly form in the presence of iron and sulfide in anoxic conditions. As such, FeS species are the main precursors for the formation of other iron sulfides such …

Zircon (ZrSiO4) is a mineral of singular importance in Earth science, the most widely used mineral in U-Pb geochronology in various geological contexts [1], including high-temperature and high-pressure events (e.g. impact events), and the oldest mineral ever found on Earth. However, the …

Abstract Narrow gaps between coupled plasmonic nano‐particles show strong optical field enhancements and spectrally adjustable resonance positions, making them attractive for surface enhanced spectroscopies. Gold nanorod dimers formed from nanorod solutions with narrow size distributions are intensely investigated in this context. However, …
