Misfit heterojunctions formed by van der Waals (vdW) epitaxial growth of one crystalline metal chalcogenide monolayer on another was demonstrated for the first time to form p-n junctions that exhibit a photovoltaic response.
Scientific Achievement
Inelastic neutron scattering (INS) studies of water sorbed on tin oxide (SnO2, cassiterite) nanoparticle surfaces at low humidity and ab initio molecular dynamics (AIMD) simulations were independently analyzed to extract the vibrati
The advancement of a hybrid atomic force microscopy/mass spectrometry imaging platform demonstrating, for the first time, co-registered topographical, band excitation nanomechanical, and mass spectral imaging of a surface using a single instrument is repor
An effective approach to sulfate separation from aqueous solutions was developed based on crystallization of sulfate-water clusters with a simple ligand self-assembled in situ from water-soluble subcomponents.
A hypercrosslinked polymer was synthesized by a Friedel-Crafts alkylation of a phenolic resin with a robust mesoporous framework to avoid framework shrinkage and maximize retention of organic functional groups.
ORNL researchers successfully developed a so
Spatial localization of distinct photoexcited species were identified in light harvesting perovskite based materials using ultrafast transient absorption microscopy (TAM).
Thallium-doping (5%) of BaFe2As2 crystal causes a surprising rise of the antiferromagnetic transition temperature (TN), related to magneto-elastic coupling. This is the first example of the increase of TN with chemical doping in BaFe2As2.
Helium implantation allows for continuous control of optical band gaps in semiconducting films through the resultant strain — an impossibility with traditional strain engineering.
