Doping-controlled topological superconducting transition in misfit layer compounds

Hugo Le Du, Robin Salvatore, Justine Cordiez, Ludovica Zullo et autres

Achieving topological superconductivity is a key goal in quantum physics, offering a path to fault-tolerant quantum computers. A central challenge in this field is to continuously drive a material through a topological quantum phase transition to directly observe the evolution from trivial …

Tuning the Charge Transfer of Transition Metal Dichalcogenides via Misfit Layer Compounds

Hugo Le Du, Ludovica Zullo, Justine Cordiez, Robin Salvatore et autres

ABSTRACT Misfit layer compounds (MLCs) are a versatile platform for exploring the electronic phase diagram of two‐dimensional (2D) materials beyond the limits of conventional gating techniques. This work demonstrates the precise tunability of electron doping in monolayers through chemical alloying within the …

Doping tunable charge density waves in misfit layer compounds

Hugo Le Du, Ludovica Zullo, Justine Cordiez, Robin Salvatore et autres

The ability to tune charge density waves (CDWs) through external control knobs, such as doping, pressure or strain is crucial for exploring the phase diagram of two dimensional (2D) or quasi-2D materials. Yet, controlling CDWs critical temperature and ordering vector remains a …

T -square electric resistivity and its thermal counterpart in RuO 2

Florent Pawula, Ramzy Daou, Benoît Fauqué, Kamran Behnia

We present a study of low-temperature electric and thermal transport in ${\mathrm{RuO}}_{2}$, a metallic oxide which has attracted much recent attention. Careful scrutiny of electric resistivity reveals a quadratic temperature dependence below $\ensuremath{\sim}20$ K undetected in previous studies of electronic transport in …

Towards photoinduced insulator-to-metal phase transition in paramagnetic Mott insulators

B. Corraze, Julio Guzman, Étienne Janod, Dorian Lagrève et autres

Global digital technology consumes ~10% of the world’s electricity. Energy efficiency could improve by moving from Von Neumann architectures to neural-network-based computing. Mottronics exploits the insulator-to-metal transition (IMT) in Mott materials for devices like memories, synapses, and neurons. Electric pulses induce the …

Enhancing thermoelectric efficiency of GeTe through process improvement via active learning assisted by Bayesian optimisation

Florent Pawula, Mathias Hamitouche, Linda Abbassi, Agathe Bajan et autres

Pristine GeTe is an archetypal mid-temperature thermoelectric, but its full potential is obscured by an eleven-dimensional process space. We combine active learning with Bayesian optimisation (ALBO) to traverse this landscape, encompassing melt-annealing and spark-plasma-sintering conditions. Starting from five random experiments, ALBO iteratively …

Multiband transport in RuO 2

Florent Pawula, Ali Fakih, Ramzy Daou, S. Hébert et autres

While ruthenium dioxide has been cited as the canonical realization of the altermagnetic state, many recent experimental probes are at odds. Here, the authors demonstrate that transport in single crystals shows no sign of a transition to an altermagnetic state over an …

Structural, optical, and electronic properties of single crystals of 4H lead-based hexagonal hybrid perovskite

Florent Pawula, Ali Fakih, Stanislav Péchev, Ramzy Daou et autres

Lead halide hybrid perovskite single crystals have been grown using antisolvent vapor-assisted crystallization. The chemical composition and structural model of the crystals have been established using nuclear magnetic resonance and single crystal x-ray diffraction, leading to the formula $\mathrm{F}{\mathrm{A}}_{0.9}\mathrm{M}{\mathrm{A}}_{0.1}\mathrm{Pb}{\mathrm{I}}_{2.23}{\mathrm{Br}}_{0.77}$. The hexagonal crystallographic …
