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 ...
Influence of Backbone Curvature on the Organic Electrochemical Transistor Performance of Glycolated Donor-Acceptor Conjugated Polymers
(Wiley, 2021-09-01)
Two new glycolated semiconducting polymers PgBT(F)2gT and PgBT(F)2gTT of differing backbone curvatures were designed and synthesised for application as p-type accumulation mode organic electrochemical transistor (OECT) ...
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 ...
TMDs as a platform for spin liquid physics: A strong coupling study of twisted bilayer WSe2
(American Institute of Physics, 2022)
[EN] The advent of twisted moire heterostructures as a playground for strongly correlated electron physics has led to a plethora of experimental and theoretical efforts seeking to unravel the nature of the emergent ...
Crystallization and Morphology of Triple Crystalline Polyethylene-b-poly(ethylene oxide)-b-poly(ε-caprolactone) PE-b-PEO-b-PCL Triblock Terpolymers
(MDPI, 2021-09-16)
The morphology and crystallization behavior of two triblock terpolymers of polymethylene, equivalent to polyethylene (PE), poly (ethylene oxide) (PEO), and poly (ε-caprolactone) (PCL) are studied: PE227.1-b-PEO4615.1-b-PCL3210.4 ...
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 ...
Polymeric materials with multiple crystalline phases: structure, morphology and crystallization
(2021-12-01)
El objetivo de esta tesis doctoral es el análisis y la comparación de sistemas poliméricos multifásicos con al menos dos fases cristalizables, para diseñar y desarrollar nuevos materiales con propiedades mejoradas. La ...
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 ...
Self-assembly and optical properties of gold nanoparticle superlattices for surface-enhanced Raman spectroscopy.
(2021-06-07)
Esta tesis se centra en la fabricación y la caracterización óptica de clústeres de nanopartículas ordenados periódicamente, es decir super-redes plasmonicas, de cara a su uso como sustratos para espectroscopia Raman ...
