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 ...
Rheology and Tack Properties of Biodegradable Isodimorphic Poly(butylene succinate)-Ran-Poly(ε-caprolactone) Random Copolyesters and Their Potential Use as Adhesives
(MDPI, 2022-02-06)
The sole effect of the microstructure of biodegradable isodimorphic poly(butylene succinate)-ran-poly(ε-caprolactone) random copolyesters on their rheological properties is investigated. To avoid the effect of molecular ...
Native point defects and their implications for the Dirac point gap at MnBi2Te4(0001)
(Nature Research, 2022)
[EN] We study the surface crystalline and electronic structures of the antiferromagnetic topological insulator MnBi2Te4 using scanning tunneling microscopy/spectroscopy (STM/S), micro(mu)-laser angle-resolved photoemission ...
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 ...
How is silicic acid transported in plants?
(Springer, 2020-11)
Plants accumulate silicon in their tissues as amorphous silica. The form of silicon taken up by plants is silicic acid, a neutral molecule that passes through membrane channels with water. After seminal work on rice ...
Excited-state band structure mapping
(American Physical Society, 2022-02-15)
[EN] Angle-resolved photoelectron spectroscopy is an extremely powerful probe of materials to access the occupied electronic structure with energy and momentum resolution. However, it remains blind to those dynamic states ...
Surface Roughness Enhances Self-Nucleation of High-Density Polyethylene Droplets Dispersed within Immiscible Blends
(American Chemical Society, 2022)
[EN] Highly linear or high-density polyethylenes (HDPEs) have an intrinsically high nucleation density compared to other polyolefins. Enhancing their nucleation density by self-nucleation is therefore difficult, leading ...
Nanometer-Scale Lateral p–n Junctions in Graphene/α-RuCl3 Heterostructures
(American Chemical Society, 2022)
[EN] The ability to create nanometer-scale lateral p-n junctions is essential for the next generation of two-dimensional (2D) devices. Using the charge-transfer heterostructure graphene/alpha-RuCl3, we realize nanoscale ...
Nanostructural Organization of Thin Films Prepared by Sequential Dip-Coating Deposition of Poly(Butylene Succinate), Poly(ε-Caprolactone) and Their Copolyesters (PBS-ran-PCL)
(Elsevier, 2021-06-04)
In this work, we prepare and characterize multiphasic thin films containing poly(epsilon-caprolactone), PCL, poly (butylene succinate), PBS, and a poly (butylene succinate-ran-epsilon-caprolactone) (PBS-ran-PCL) random ...
