How dry is dry? Molecular mobility in relation to thallus water content in a lichen
(Royal Society Of Chemistry, 2020-11-07)
The increasing demand for nanoscale magnetic devices requires development of 3D magnetic nanostructures. In this regard, focused electron beam induced deposition (FEBID) is a technique of choice for direct-writing of complex ...
Effect of environmental humidity on the ionic transport of poly(ethylene oxide) thin films by local dielectric spectroscopy
(RSC, 2020-03-03)
The effect of humidity on the ionic transport in the amorphous phase of poly(ethylene
oxide) thin films has been studied by via local dielectric spectroscopy. We explored a
controlled humidity range between 15 %RH and ...
Interplay of Topological States on TI/TCI Interfaces
(MDPI, 2020-10-10)
Based on first-principles calculations, we study electronic structure of interfaces between a Z2 topological insulator (TI) SnBi2Te4 and a topological crystalline insulator (TCI) SnTe. We consider two interface models ...
Fabrication of a Novel Magnetic Topological Heterostructure and Temperature Evolution of its Massive Dirac Cone
(Nature, 2020-09-24)
Materials that possess nontrivial topology and magnetism is known to exhibit exotic quantum phenomena such as the quantum anomalous Hall effect. Here, we fabricate a novel magnetic topological heterostructure Mn4Bi2Te7/Bi2Te3 ...
Chemistry in Quantum Cavities: Exact Results, the Impact of Thermal Velocities, and Modified Dissociation
(American Chemical Society, 2020-09-17)
In recent years tremendous progress in the field of lightmatter interactions has unveiled that strong coupling to the modes of an optical cavity can alter chemistry even at room temperature. Despite these impressive advances, ...
Direct Observation of Desorption of a Melt of Long Polymer Chains
(Nature, 2020-08-28)
Tuning the thermodynamic state of a material has a tremendous impact on its performance. In the case of polymers placed in proximity of a solid wall, this is possible by annealing above the glass transition temperature, ...
Tunable Photodetectors via In Situ Thermal Conversion of TiS3 to TiO2
(MDPI, 2020-04-09)
In two-dimensional materials research, oxidation is usually considered as a common source for the degradation of electronic and optoelectronic devices or even device failure. However, in some cases a controlled oxidation ...
Coarsening Kinetics of Complex Macromolecular Architectures in Bad Solvent
(MDPI, 2020-03-02)
This study reports a general scenario for the out-of-equilibrium features of collapsing polymeric architectures. We use molecular dynamics simulations to characterize the coarsening kinetics, in bad solvent, for several ...
Polycyclic aromatic chains on metals and insulating layers by repetitive [3+2] cycloadditions
(Nature Publishing, 2020-03-20)
The vast potential of organic materials for electronic, optoelectronic and spintronic devices entails substantial interest in the fabrication of -conjugated systems with tailored functionality directly at insulating ...
Octopus, a computational framework for exploring light-driven phenomena and quantum dynamics in extended and finite system
(American Institute of Physics, 2020)
Over the last few years, extraordinary advances in experimental and theoretical tools have allowed us to monitor and control matter at short time and atomic scales with a high degree of precision. An appealing and challenging ...
