Femtosecond-laser direct-write photoconductive patterns on tellurite glass
Yves Bellouard, Gözden Torun, Anastasia Romashkina
We report the formation of arbitrary photoconductive patterns made of tellurium (Te) nanocrystals by exposing a tellurite (TeO2-based) glass to femtosecond laser pulses. During this process, Te/TeO2-glass nanocomposite interfaces with photoconductive prope ...
2024Ancestral genome reconstruction enhances transposable element annotation by identifying degenerate integrants
Didier Trono, Evaristo Jose Planet Letschert, Wayo Matsushima
Growing evidence indicates that transposable elements (TEs) play important roles in evolution by providing genomes with coding and non-coding sequences. Identification of TE-derived functional elements, however, has relied on TE annotations in individual s ...
2024Formation Mechanism of Elemental Te Produced in Tellurite Glass Systems by Femtosecond Laser Irradiation
The formation of elemental trigonal tellurium (t-Te) on tellurite glass surfaces exposed to femtosecond laser pulses is discussed. Specifically, the underlying elemental crystallization phenomenon is investigated by altering laser parameters in common tell ...
2023Murunskite - a new class of functional material
The subject of the present work is discovery and in-depth characterization of a new class of functional materials. Tuning of the bond polarity and orbital occupation with a goal of establishing balance between localization and delocalization of electrons - ...
EPFL2023Modeling high-entropy transition metal alloys with alchemical compression
Michele Ceriotti, Guillaume André Jean Fraux, Sandip De, Nataliya Lopanitsyna
Alloys composed of several elements in roughly equimolar composition, often referred to as high-entropy alloys, have long been of interest for their thermodynamics and peculiar mechanical properties, and more recently for their potential application in cat ...
AMER PHYSICAL SOC2023Modelling of metal alloys in realistic conditions with machine learning
Computer simulations based on statistical methods have emerged as a powerful tool for studying structure-property relationships at the atomistic level. However, to provide reliable insights into materials in realistic conditions, it is essential to accurat ...
EPFL2023Femtosecond laser-induced modifications and self-organization in complex glass systems
Ultrashort laser pulses, i.e., pulses emitted shorter than a picosecond, can tailor material properties by introducing permanent modifications locally in three dimensions. Remarkably, under a certain exposure condition, these modifications are accompanied ...
EPFL2023Preparation of amorphous bismuth films by quenched condensation insode of a superconducting magnet
Topological phases in crystalline materials have drawn intense research interest due to their fundamentally unique properties and potential for applications ranging from quantum computation to spintronics. Recently, scientists have extended the theoretical ...
2022Direct-write laser-induced self-organization and metallization beyond the focal volume in tellurite glass
We report on a self-organized process initiated on a potassium-tungsten-tellurite glass surface under repetitive femtosecond laser irradiation in a regime where cumulative effects lead to a localized melting. Specifically, we show that self-organized perio ...
2021Atom-surface van der Waals potentials of topological insulators and semimetals from scattering measurements
The phenomenology of resonant scattering has been known since the earliest experiments upon scattering of atomic beams from surfaces and is a means of obtaining experimental information about the fundamentals of weak adsorption systems in the van der Waals ...
