Spin-wave eigenmodes in direct-write 3D nanovolcanoes
(American Institute of Physics, 2021-03-28)
Extending nanostructures into the third dimension has become a major research avenue in modern magnetism, superconductivity, and spintronics, because of geometry-, curvature-, and topology-induced phenomena. Here, we ...
Engineering Three-Dimensional Moire Flat Bands
(American Chemical Society, 2021-09-22)
Twisting two adjacent layers of van der Waals materials with respect to each other can lead to flat two-dimensional electronic bands which enables a wealth of physical phenomena. Here, we generalize this concept of so-called ...
Preparation, Physical Properties, and Applications of Water-Based Functional Polymer Inks
(MDPI, 2021-04-27)
In this study, water-based functional polymer inks are prepared using different solvent displacement methods, in particular, polymer functional inks based on semiconducting polymer poly(3-hexylthiophene) and the ferroelectric ...
Screening in Graphene: Response to External Static Electric Field and an Image-Potential Problem
(MDPI, 2021-06-13)
We present a detailed first-principles investigation of the response of a free-standing graphene sheet to an external perpendicular static electric field E. The charge density distribution in the vicinity of the graphene ...
Electronic Temperature and Two-Electron Processes in Overbias Plasmonic Emission from Tunnel Junctions
(American Chemical Society, 2021-08-25)
The accurate determination of electronic temperatures in metallic nanostructures is essential for many technological applications, like plasmon-enhanced catalysis or lithographic nanofabrication procedures. In this Letter, ...
Platinum(IV)-azido monocarboxylato complexes are photocytotoxic under irradiation with visible light
(Royal Society Of Chemistry, 2021-08-14)
Complexes trans,trans,trans-[Pt(N-3)(2)(OH)(OCOR)(py)(2)] where py = pyridine and where OCOR = succinate (1); 4-oxo-4-propoxybutanoate (2) and N-methylisatoate (3) have been synthesized by derivation of trans, trans,tran ...
Additive Effect on the Structure of PEDOT:PSS Dispersions and Its Correlation with the Structure and Morphology of Thin Films
(MDPI, 2021-12-30)
We reported on the interaction between poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) and high-boiling-point additives in PEDOT:PSS aqueous dispersions and in the final polymer films with the aim of ...
Ab Initio Theory of Photoemission from Graphene
(MDPI, 2021-05-03)
Angle-resolved photoemission from monolayer and bilayer graphene is studied based on an ab initio one-step theory. The outgoing photoelectron is represented by the time-reversed low energy electron diffraction (LEED) state ...
Engineered Magnetization and Exchange Stiffness in Direct-Write Co-Fe Nanoelements
(American Institute of Physics, 2021-01-11)
Media with engineered magnetization are essential building blocks in magnonics, spintronics, and superconductivity. However, the established thin film and lithographic techniques insufficiently suit the realization of ...
Moireless Correlations in ABCA Graphene
(National Academy of Sciences, 2021-01-26)
Atomically thin van der Waals materials stacked with an interlayer twist have proven to be an excellent platform toward achieving gate-tunable correlated phenomena linked to the formation of flat electronic bands. In this ...
