Tuning the color of high-karat gold in Au-TiO2 nanoparticle composites all the way to black

László Forró, Claudio Grimaldi, Endre Horvath, Andrzej Sienkiewicz

For centuries, artisans have harnessed gold nanoparticles to imbue their creations with the vibrant hues that captivate the eye through interactions with visible light. In modern times, these distinct optoelectronic characteristics have pivoted toward the ...

Interplay between disorder and electronic correlations in compositionally complex alloys

László Forró, Jan Hugo Dil, Luka Ciric, Edoardo Martino, Xavier François Mettan, Trpimir Ivsic, Davor Tolj

Owing to their exceptional mechanical, electronic, and phononic transport properties, compositionally complex alloys, including high-entropy alloys, represent an important class of materials. However, the interplay between chemical disorder and electronic ...

Electron Glass Phase with Resilient Zhang-Rice Singlets in LiCu3O3

Rosario Scopelliti, László Forró, Henrik Moodysson Rønnow, Arnaud Magrez, Krunoslav Prsa, Simon Karl Moser, Paul Gregory Freeman, Jens Christian Johannsen, Gianmarco Gatti, Edoardo Martino

LiCu3O3 is an antiferromagnetic mixed valence cuprate where trilayers of edge -sharing Cu(II)O (3d9) are sandwiched in between planes of Cu(I) (3d10) ions, with Li stochastically substituting Cu(II). Angle resolved photoemission spectroscopy (ARPES) and de ...

Perovskite-based detector for reactor dosimetry monitoring

László Forró, Andreas Pautz, Endre Horvath, Pavel Frajtag, Péter Szirmai, Márton Kollár

Hybrid halide perovskites have demonstrated significant efficiency in detecting a broad spectrum of high-energy radiation, including X-rays, gamma rays (γ-rays), and neutrons. Given the common occurrence of mixed radiation fields, we investigated the perfo ...

Terahertz emission from diamond nitrogen-vacancy centers

László Forró, Ferenc Simon, Bence Gábor Márkus, Sándor Kollarics

Coherent light sources emitting in the terahertz range are highly sought after for fundamental research and applications. Terahertz lasers rely on achieving population inversion. We demonstrate the generation of terahertz radiation using nitrogen-vacancy c ...

Effect of the Deposition of Vanadium-Oxide on the Photocatalytic Activity of TiO2 Nanotubes and Its Photodiode Performance Interfaced with CH3NH3PbI3 Single Crystal

László Forró, Endre Horvath, Pavao Roko Andricevic

In this study, we report the influence of vanadium oxide (VO), as a photosensitive component, on the photoactivity of TiO2 nanotubes (TNTs). A series of TNTs of varying tube diameter were synthesized by the anodization of titanium foils at different voltag ...

Origin of Subgap States in Normal-Insulator-Superconductor van der Waals Heterostructures

László Forró, Helmuth Berger

Superconductivity in van der Waals materials, such as NbSe2 and TaS2, is fundamentally novel due to the effects of dimensionality, crystal symmetries, and strong spin-orbit coupling. In this work, we perform tunnel spectroscopy on NbSe2 by utilizing MoS2 o ...

Ultralong 100 ns spin relaxation time in graphite at room temperature

László Forró, Bálint Náfrádi, Péter Szirmai, Bence Gábor Márkus

Graphite has been intensively studied, yet its electron spins dynamics remains an unresolved problem even 70 years after the first experiments. The central quantities, the longitudinal (T-1) and transverse (T-2) relaxation times were postulated to be equal ...

Electronic transport and magnetism in the alternating stack of metallic and highly frustrated magnetic layers in Co(1/3)NbS(2)

László Forró, Henrik Moodysson Rønnow, Ivica Zivkovic, Helmuth Berger, Jacim Jacimovic, Julian Piatek, Nikolay Tsyrulin

Transition-metal dichalcogenides (TMDs) are layered compounds that support many electronic phases, including various charge density waves, superconducting, and Mott insulating states. Their intercalation with magnetic ions introduces magnetic sublayers, wh ...

Solar water purification with photocatalytic nanocomposite filter based on TiO2 nanowires and carbon nanotubes

László Forró, Luca Rossi, Andrzej Sienkiewicz, Endre Horvath, Florian Frédéric Vincent Breider, Dominique Grandjean, Miriam Gaál

Water contamination due to environmental conditions and poor waste management in certain areas of the world represents a serious problem in accessing clean and safe drinking water. This problem is especially critical in electricity-poor regions, where adva ...
