Overcoming the Exciton Binding Energy in Two-Dimensional Perovskite Nanoplatelets by Attachment of Conjugated Organic Chromophores
(Nature, 2020-04-20)
In this work we demonstrate a novel approach to achieve efficient charge separation in dimensionally and dielectrically confined two-dimensional perovskite materials. Two-dimensional perovskites generally exhibit large ...
Conditional Wave Function Theory: A Unified Treatment of Molecular Structure and Nonadiabatic Dynamics
(American Chemical Society, 2021-11-09)
[EN] We demonstrate that a conditional wave function theory enables a unified and efficient treatment of the equilibrium structure and nonadiabatic dynamics of correlated electron-ion systems. The conditional decomposition ...
Nematicity Arising from a Chiral Superconducting Ground State in Magic-Angle Twisted Bilayer Graphene under In-Plane Magnetic Fields
(American Physical Society, 2021-09-13)
Recent measurements of the resistivity in magic-angle twisted bilayer graphene near the superconducting transition temperature show twofold anisotropy, or nematicity, when changing the direction of an in-plane magnetic ...
Light-Driven Extremely Nonlinear Bulk Photogalvanic Currents
(American Physical Society, 2021-09-13)
We predict the generation of bulk photocurrents in materials driven by bichromatic fields that arc circularly polarized and corotating. The nonlinear photocurrents have a fully controllable directionality and amplitude ...
Polycaprolactone Adsorption and Nucleation onto Graphite Nanoplates for Highly Flexible, Thermally Conductive, and Thermomechanically Stiff Nanopapers
(American Chemical Society, 2021-12-15)
[EN] Free-standing nanopapers based on graphene and its related materials have been widely studied and proposed for flexible heat spreader applications. Given that these materials are typically brittle, this work reports ...
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 ...
Unparalleled selectivity and electronic structure of heterometallic [LnLn′Ln] molecules as 3-qubit quantum gates
(Royal Society of Chemistry, 2022)
[EN] Heterometallic lanthanide [LnLn'] coordination complexes that are accessible thermodynamically are very scarce because the metals of this series have very similar chemical behaviour. Trinuclear systems of this category ...
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 ...
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 ...
