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 ...
Focusing of in-plane hyperbolic polaritons in van der Waals crystals with tailored infrared nanoantennas
(American Association for the Advancement of Science, 2021-10)
[EN]Phonon polaritons (PhPs)-light coupled to lattice vibrations-with in-plane hyperbolic dispersion exhibit ray-like propagation with large wave vectors and enhanced density of optical states along certain directions on ...
Microcavity phonon polaritons from the weak to the ultrastrong phonon–photon coupling regime
(Nature Research, 2021-10-27)
[EN]Strong coupling between light and matter can be engineered to influence their properties and behaviour. Here, the authors demonstrate the evolution from weak to ultrastrong coupling of microcavity modes and optical ...
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, ...
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 ...
Out-of-Plane Transport of 1T-TaS2/Graphene-Based van der Waals Heterostructures
(American Chemical Society, 2021-07-27)
Due to their anisotropy, layered materials are excellent candidates for studying the interplay between the inplane and out-of-plane entanglement in strongly correlated systems. A relevant example is provided by 1T-TaS2, ...
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 ...
Electron-phonon-driven three-dimensional metallicity in an insulating cuprate
(National Academy of Sciences, 2020-03-24)
The role of the crystal lattice for the electronic properties of cuprates and other high-temperature superconductors remains controversial despite decades of theoretical and experimental efforts. While the paradigm of ...
Bottom-up Fabrication and Atomic-Scale Characterization of Triply Linked, Laterally π-Extended Porphyrin Nanotapes
(Wiley, 2021-07-12)
Porphyrin nanotapes (Por NTs) are promising structures for their use as molecular wires thanks to a high degree of pi-conjugation, low HOMO-LUMO gaps, and exceptional conductance. Such structures have been prepared in ...
